[Q] 4cyl turbo engine NOS mod

I've been keeping my eye on this mod for sometime now and just wanted to know if any other N4 owners have installed it, on what ROM and kernel, and what their opinions are.
This device already flies pretty fast and lag free for me. Don't ever really have low mem issues. But I sure do love mods, tweaks, playing around with this device, and anything that could potentially boost performance even more.
I'm currently using XenonHD with Franco kernel r110.
Cheers and look forward to the responses and discussion.

Hi,
In my opinion do not waste time with it. I've just take a look in the init.d scripts... Some of them are not for our devices like the "touchscreen" and "kernel" (for the shed_features" parts...
The rest is... , test and see but these kinds of "turbo mega lag free extra smoothess performance with extreme RAM performance and giga boost" is to be avoided.
Make a Nandroid backup before testing with all the system files that are modified with these "all in one" scripts, be carefull to the bootloop .
With ours Nexus 4... do they really need these kinds of scripts? Like you said your device is fast and lag free, so no need of these scripts. At best it does nothing, at worst it's counter productive... and after one day after flashing this "turbo" thing you have some lags here and there... Often these scripts for RAM management are not optimized for a device with 2 gigas of RAM and JB 4.2.2, I speak about these "megacompilation" scripts and there is a bunch in the Android Software and Hacking General section. If you want to test something, maybe try V6 Supercharger at worst, and yet I'm not sure we need this...
I've tested a few of these scripts with my Gnex and SIII so I saw that there was nothing impressive at all (as for the title of these threads ) and sometimes it was the opposite (very often) or no improvement at all.
It's like all the build.prop edit for tweaks that we find with these scripts: does nothing, are obsolete, etc...
Googled for some tweaks for VM and RAM management like for some build.prop tweaks, you will be surprised about the real effectiveness
Android, for me, manages very well its RAM so I let Android manages its RAM , maybe some multitasking things to improve but with my Nexus I have not any issues with multitasking like closed apps too quickly or lags after 5 days of use without a reboot. Maybe this is how I use my phone...
So in short your phone works perfectly: don't care about this stuff and focuses you on the CPU settings with your custom kernel (Franco like you use or another one) :angel:

for 2GB RAM in nexus 4 ;
We still have 1GB RAM free, check it in running service, setting -> apps -> running service.
there is no RAM tweaks needed.
This is for device who only has 512MB but running Jelly Bean ROM, such as Nexus S , etc etc.
With QuadCore and 2GB RAM, it is really unnecessary to ahve this kind of tweaks.
There are so many developer in nexus 4 Development Thread.
You can have Customs ROM to optimize or to make more beauty for the User Interface, there are so many options.
For a bit more performance and battery savings, you can try Custom Kernel, I used Franco, It is a good Kernel, to save more battery when idle.
and also you can tweak for color saturation IPS screen, etc etc.
Its all you need.

Ya I've always been cautious when it comes to random build.prop/init.d tweaks and have used zeprox v6 supercharger on older android phones. But was hesitant on this one, despite my desire to tweak and mod to my hearts content and then some. In the OP it says confirmed working on N4 so I was just curious if anyone had actually tried it and with what results. Thanks for the response.

Hi,
Yep with some old phones with an old Android version and a low hardware compared to the Nexus 4 it can help...
With the Nexus 4 I don't see the point, but yes you can try and see if you feel that there is some improvements, but I honestly doubt.
Yes the OP said it works in the sense that there are no issues (like bootloop) it does not mean, for me, there will be some huge improvements (at least nothing or very little ...).
Personally I will no longer test these scripts since I never see any kind of improvement with my last phones...
It can improve something but can brake something else, I mean for example smoother UI but lagger games, better experience in X or Y situation but your battery will be killed faster, etc... yes it exists
If you like playing with some tweaks and maybe you can find some good results by modifying some values in these scripts but not like as they are here.Try but it takes a lot of time and you need to do some search like on some Android / Linux forum to understand how Android works (and not on a forum or threads with a "turbo mega giga smoother faster script ever seen with NOS injection RAM script of the death" as title :laugh: , other than that... It's worth playing with your CPU settings, governors. At least for me.
And keeps in mind that with these kind of scripts that promise better battery life with much better performance, there is a moment where these two things are not compatible (in certain proportions). If you realy want some extra perfs, you'll need to sacrify the battery life and vice versa

Gaming on the Find 5

Hello fellow Find 5 friends! ( say that 5 times fast :laugh: )
As we all know the Find 5 packs a:
Qualcomm S4 Pro APQ8064
Krait 200 CPU: 4 cores @ 1.5GHz
Adreno 320: 400MHz
2GB RAM @ 533 MHz dual channel
Click to expand...
Click to collapse
in its belly, and shares this with quite a list of phones:
Asus PadFone 2
HTC Droid DNA
HTC J Butterfly
LG Optimus G
Nexus 4
Pantech Vega No.6
Pantech Vega R3
Sharp Aquos Phone Zeta
Sony Xperia UL
Sony Xperia Z
Sony Xperia ZL
Sony Xperia ZR
Xiaomi MI-2
Panasonic P-02E
Note that some new devices (the Nexus 7 2013 is a good example) has a "S4 Pro" SoC in the spec sheet, but is actually a lower-binned / lower-clocked 600 chip [APQ8064–1AA to be exact] and uses Krait 300 CPU cores and therefore outperforms its Krait 200 cousins in the Nexus 4 / Find 5 / etc.
The silicon is quite formidable- and led pack until the release of Qualcomm's 600 and 800 chips. Although some argue that the Adreno 320 is slightly underpowered for 1080p, the point is the Find 5 packs alot of power.
However despite this custom ROM gaming performance was poor initially:
Entropy512 said:
Some games apparently hang the device. Others, such as Ingress, work perfectly.
Problem is our display subsystem is a really nasty hackjob that is a mix of early 4.1 source code (Oppo's original baseline) and 4.2 stuff. Ideally, it will eventually be a pure CAF jb2.5 branch baseline - this is what most other CM devices are on or going to. Some stuff is easy to rebase, some is harder. I have a feeling I'm probably going to fix the camera the same way as the Sony and Samsung guys did it - copypasta the entire camera subsystem drivers from the original baseline and use those. (The camera drivers in the kernel seem isolated enough that it works fine on Samsung and Sony qcoms.) Biggest thing is the power management, especially charging - Oppo made major changes here to Qualcomm's early-4.1 baseline, AND Qualcomm made major changes to this code. As a result, getting that stuff right and properly merged is gonna be a PITA. It's sort-of-barely working in the codebase on my personal github, but it's doing all sorts of stuff it shouldn't, and also not doing stuff it should (like charging from USB). The standby power drain is also insane, which is strange since the newer CAF codebase should be MORE power efficient, not less.

However since the 4.2 kernel rebase gaming performance has dramatically improved in my testing. This no doubt is related to all the kernel display changes work from our wonderful developers made possible by Oppo who released the sources for 4.2..
So pick up a ROM / kernel combination that has this 4.2 goodness and feel improvements across the board! Here is a list of the ROMs:
Color ROM [formerly known as Project Firefly] v1.0.0_33xx and later
Maxwen's AOKP 20130810 and later
CM10.1 Official Nightly 20130810 and later
CodefireX
IMPORTANT NOTE- CUSTOM ROMS USE THE 4.1 MODEM FIRMWARE
This means if you've flashed a 4.2 Color ROM and want to move to a custom ROM, you MUST flash the modem firmware from a 4.1 Color ROM before flashing a custom ROM or else WIFI WILL NOT WORK. Simply flash the 4.1 Color ROM (or the firmware package) and then flash the custom ROM immdediately after, you do not need to boot the 4.1 Color ROM.
Now back to the actual thread, I thought it would be helpful to compile a master list of games that work and don't work (for whatever reason) and use this as a future reference and for troubleshooting. Feel free to contribute: just the game name, your experience on it and if possible your ROM / kernel configuration.
My device settings:
Latest Maxwen AOKP / kernel
MP-Decision: Off
Multicore Power Saving: 0
CPU: 162MHz / 1.134 GHz
Governor: smartmax_eps
CPUQuiet: load_stats

EMULATORS
With the release of DraStic I felt it was time to add a section for emulators. I will list them by console rather than app.
DS
DraStic is my emulator of choice. I'll leave the feature list to the developer, but the biggest draw is that it is very fast. Since version 2.1.1a (released 8/1x/2013) the DS BIOS file is no longer needed for unencrypted ROMs. If my word (and the word of many across the internet) is not enough to convince you to drop $8, there is a demo version of the app (full functionality, 20 minute limit)
Some select quotes from the FAQ:
Q: Does DraStic support 3DS games? Will it in the future?
A: No, it does not and never will. 3DS is an entirely different system, a full generation ahead, like N64 to Gamecube.
Click to expand...
Click to collapse
Q: How fast should I expect DraStic to be?
A: It varies greatly depending on the game you're trying to run. A device with 1GHz Cortex-A8 will run many games with a fair amount of frameskip. A 1.4+GHz dual-core Cortex-A9 will run most games with little or no frameskip most of the time.
Click to expand...
Click to collapse
Q: Does it help to have multiple CPU cores?
A: Yes. If you have multiple cores DraStic is sped up by being able to offload screen update tasks to another thread. If you select the multi-threaded renderer option you will get even more benefit, but this option can cause graphical glitches and instability.

Click to collapse
Q: Are MOGA controllers supported?
A: It is possible to make it work by installing Moga Universal Driver from Google Play. We are currently working on including native support.
Click to expand...
Click to collapse
Q: Does DraStic use my GPU to render graphics? Does it help to have a faster GPU
A: The GPU is only used to scale the image and apply filters so having a better one won't make much difference. OpenGL ES is not used to render the Nintendo DS graphics. This is because of idiosynchracies in the DS graphics hardware that would make this style of emulation incomplete and/or slow.

Click to collapse
Q: Does DraStic support homebrew games?
A: Currently many homebrew games are not supported because DraStic does not yet support DLDI filesystem integration which many homebrew games rely on. This is a planned feature for a later date.

I have only played a few games (namely ones that have simple controls) and they have been flawless.
My settings:
Frameskip: Auto [4]

Well I don't game much but even the lightest game I play, Rage of Bahamut, lags worse than on any other Handset I tried it.
Also I have to admit that on AOSP Roms even the interaction with the UI feels like there is something wrong with the phone. Compared to a Nexus 4 or a S3 or S4 the UI lags or slows down everywhere from time to time...

I don't play many games, in fact I only play Tekken Card Tournament. But since I have got my Find 5 the game always crash my phone, sometimes already after seconds.
Hope the devs will fix this soon and get the phone stable. Currently using cm10.1 and maxwen kernel.
Sent from my Find 5 using xda app-developers app

Updated OP with some new findings and reports from other users and developers. Found a fix for the performance issues (ended up being an extension of a weird interaction I found)
Basically, if the game / application lags, turn the screen off and on again without exiting the application- upon resuming the lag should be gone!

House of the Dead
+ Playable, seem to run smooth at high fps.
+ Responsive controls.
- Random crashes (general game issue, not device or rom).
Street Fighter 4
+ Playable, high fps
- Audio feedback delayed

Gaming performance on color rom.is much better than previous roms

I have one positive report on oppoforum that with latest test
kernel games issues are gone
please give it a try and report back

that's great news, unfortunately for me I still get low frame rate, although it seems better than before.

I have to admit that I lost your last log somewhere
I would need both a logcat and a kernel log
simply attach your device via adb and run
Code:
adb logcat
adb shell dmesg
copy the output of both commands into a file and upload it

I think I'm doing something wrong- I have the device connected via adb, then I launch the game and start the logcat / desg (adb logcat < log.txt). The device hard reboots after about 10 seconds. After it finished I run (adb shell cat /proc/last_msg > kmsg.txt) to get the last_kmsg
Oddly the frame rate is actually better while connected to ADB and logging then normal (of course nowhere close to post screen on/off).

Well - the low framerate is because device is spilling to logs
and that slows down everything
Right now I am unable to identify a change in CAF that "could" fix this issue
Problem is also that I still dont have an easy way to reproduce this here
so I can not even do some trial-and-error things.

Of course I/O and CPU would be spent logging and frame rate would suffer, but when I was testing the FPS was actually higher than it is usually even with the logging in process- maybe because it was plugged in through USB?
Did I do the logs correctly? I don't know why my logs are so damn big!

Okay excellent, I'll install the free version, and report back in 10 minutes with a log if I see frame rate issues after a clean reboot, would that help?
I also suspect I have the Chinese version (seller wasn't clear)- according to Oppo there is only a band difference (1700)- but maybe thats a hidden confounding variable?

Lag solutions

I've seen a good amount of people complaining about lag, so i thought i'd share what i've done to get my g3 running smoothly.
* See below for kernel settings
First off I rooted my d850 with towelroot. Using titanium backup, I froze all at&t apps along with apps I don't use like kindle, uber, beats music. Also froze messages back & sync since it was always running, and I backup up my texts manually.
Everything I froze:

Now there's the whole art debate. I have noticed a big improvement in smoothness and battery life using art, but there's also compatibility issues with some apps, and xposed. When switching back to dalvik runtime you can definitely see some general UI stuttering, here's what can be done.
Kernel settings
I installed (and highly recommend) Kernel Toolkit and played around with a few settings. You'll have to install busybox too which worked fine. KEEP IN MIND we don't have a recovery to save our asses in case of bootloops so if you make any changes in trickster do so at your own risk, and when using set on boot, apply a long enough delay for you to fix any bootloops in the event that your phone doesn't like your settings.
That being said I would be surprised if anyone manages to find settings that causes reboots on the stock kernel, given that theres no voltage table to mess up, or any unique cpu governers.
Onto my settings:
I/O scheduler = cfq
Governor control (with interactive governor) -> hispeed_freq = 1267200
Here are some other changes you can make in governor control for better performance:
go_hispeed_load - change from 90 to 85
min_sample_time - change from 40000 to 50000
target_loads - change from 85 to 80 or 75 (75 = better performance)
NOTE: I have tested my settings for a few days and they seem to be stable. If you want even better performance (at the cost of some battery life) you can try some more changes DON'T use the set on boot option until you're sure they don't cause reboots! Once you deem them stable you should use set on boot with a 30 second delay. Without the set on boot option you'll have to manually reapply your settings after every bootup as kernel settings get set back to default on boot.
NOTE: I've found using the ondemand governor causes reboots.
With these settings i'm not missing art anymore. I've found that setting the scheduler to cfq takes care of most of the lag. Keep in mind that tweaking the kernel for better performance USUALLY comes at the cost of a little battery life. So you'll have to find a sweet spot that your happy with in terms of performance and battery life. Feel free to discuss and share your kernel settings

I'm probably the only one experiencing more lag with ART than not. With ART enabled my G3 was stuttering everywhere and I had to pull the battery ~3 times in 2 hours because the screen just wouldn't turn on.
It's silky smooth on dalvik though, lol

Yeah sounds like compatibility issues with some of your apps.

Tested ondemand governor, caused reboots.

Surely a third party launcher will just sort all lag issues out?

Why would it do that? Of course it helps with launcher lag but not with lag occuring in menus etc.
Oh and thanks to Heisenberg! Tried your settings and with art enabled everything works nice and smoothly. No more stuttering.

Please let us know how stable these settings end up being. Thanks!

I think people are getting confused over what is lag and what is not.
Lag is when the UI is delayed when it shouldn't be - this can be caused by a number of factors including wrong cpu clock speeds, overheating or lack of quality ram management (usually due to one or two poorly coded apps eating everything up!)
What most of you are experiencing on Dalvik is not lag, its just the way the JIT compiler works, apps on Dalvik will take a split second to open while it compiles what it needs, generally speaking this is not noticable, but we all know people on XDA always notice everything....
If you are experiencing lag then it is most likely caused by something other than Dalvik the ART build on this device is outdated doesn't offer anything (seriously!) over Dalvik, this in no way reflects what we will see on Android L.

My g3 suffers terribly from redraw it just should not be happening on something this powerful

I had some noticable stuttering in many actions like in menus and scrolling. After changing to ART and enabling these tweaks they are gone. Placebo or not I'm happy with the results, no stutters or lag of whatever you want to call it I'm aware the ART included is nothing like ART on L, but to me it just helps that little bit.

That's placebo.
ART only affects lag, that is the time between pressing on an icon and the app opening. ART pre compiles the bytecode needed to run an app beforehand thus eliminating the need to do it on the fly which dalvik does (it should also improve battery life as converting it to bytecode takes cpu cycles). It doesn't do anything for stutter or scrolling. By yeah the ART in 4.4.2 is old code as well and not optimized yet so there will be little improvement in lag also.

So be it. It doesn't matter to me if its placebo or not. Feels nicer to use and that is what matters.

Still not getting the ART love. For milli seconds of improvement you lose 25% of storage space. Not seeing the net positive at all, but a big a$$ net negative.

I will miss Xposed if they can't get it to work right on ART

I'll try your guide. Lag and redraw is not what I prefer in a new flagship. Art is more than placebo, it's notable better but I'll like to use Xposed.

SadLy true

Seems to do some difference. Even with art I had some lag in app drawer and it seems to be gone. Placebo or not, it's feels a bit more snappy in app drawer so that's another one to beat the dust ? So far I'll keep art on, I have loads of space and launcher and apps are notable snappier with it in. Its not like my M8 but it's a bit closer.

art
Sorry for a very noobish question, but can someone tell me what art is? I got my lg g3 last week and quiet playing a bit with it. I got the international version 3/32gb (LG-D855 V10a) and wanted to root it to somehow boost my battery life. Its fine and my battery can last a day with my normal usage and im very happy with it (waaaaaay much better than my ip5), but if i can squeeze more juice and make it last a day and a half or even more, im willing to root and take full pledge over my device.
I also experience having error that my device is heating up and won't be able to max out brightness, weird coz when it happen im actually doing nothing with my device, i just adjust brightness and it wont let me to max it out, so as of now im considering it as a bug and hoping that an update will fix it. It does warm up a bit but not the same as my toasty galaxy note 2 and galaxy s4 so i can live with it, but if i can remove the energy being waste and boost battery life by rooting it, ill forget OTA.
Anyway, back to my main concern,,, what is art? Hue hue

Hey mate. Art is android run time. Do a quick google search on how to change it or one of the pro's on here can go into the finer details on the benefits of using it.

Dolphin Emulator Nvidia Shield Tablet

Hello everyone,
I'm very sad to see how this section and developpement section is empty. I bought the Shield Tablet because she have many possibilities for a tablet(GC/Wii emulation with Dolphin for exemple) and i'm very sorry to see no one really care about this device.
It is on Dolphin that I want to make a point.
Ryan Houdek(Alias Sonicadvance in this forum) work for long months on Dolphin Emulator for Android. It allowed us to see that emulation was quite possible on Tegra K1 processors.
After a massive work on Armv7 JIT, Ryan worked on Aarch64(aka Armv8) because many arm devices will release this year.
Many games because playable with Fiora "overclock" fonction. There is a list and somes examples

I work too on Dolphin Emulator and bring it a little speed up for playing at Wind Waker.

Since a few days, Ryan work on a Vertex Loader in NEON(NEON are +/- = SSE3). This will give a good boost to any games limited by the loader vertex. (understand gpu thread).
After that, he will work on a Texture decoder(in NEON too). Same think than the Vertex Loader.
Somes games will quickly become playable, like Zelda Wind Waker, Zelda Twilight Princess, Super Mario Sunshine and many many others.
I continue my work for the Shield Tablet, i've actually no plan to bought others tablets. I just want to play at somes games on my Shield Tablet.
So if you wanna play GC/Wii Games on Shield Tablet, please support us. There are many things that you can do.
For devs :
- Write a Texture Decoder in x86 or NEON(this is easy to translate x86 to NEON)
- Bring an overclocking function for the Shield, 2,5Ghz is great for boost and safety
- Help to developping Dolphin Emulator(resolve crashs, enhance function, etc)
For users :
- Report bugs
- Like this postP)
- Show us how many want that, that's very motivating

I am not a dev, but I am delighted and amazed to read this post. I, personally, thought we would have to wait for the X1 to emulate full gamecube and wii games.
But this is just another victory and proof that the Nvidia Shield Tablet is largely under-developed and has great great potential.
EDIT: You should rename the title of the post, to a more fitting name for everyone to see

Thats awesome dude !
i too bought the shield as it seemed to have lots of possibilities, i keep 2-3 forums open and i check daily and i have been disappointed as well how little attention it has got.

Little update, with the lasts fixs from Ryan and me there is good improvements. No more crashs on many games(like ZWW, ZTP, SMS, and many others). Weirds textures fixed on somes games(like Fire Emblem, Digimon Rumble Arena, etc)
Many optimisations.

I am very interested in some new development for the shield! Best of luck in your efforts and I would love to be able to play TP on the shield.

Great Projet
The shield tablet is a good device for this project, emulate a gamecube archictecture in ARM is difficulte but is not impossible. Good luck fort the next

Wow! This is so exciting, I can't wait to see how this project comes along. Will be watching closely
Sooo many kudos OP! Like, millions of them!

Great project! Hopefully, we'll all be able to play Smash on our shields soon.

Nice i will test that soon as possible. Based of last kernel for Nvidia Shield Tablet ?
Edit : Some voltages are a bit higher, you can easily reduce them. Clock is locked to 2397Mhz. I added somes comments on your work.

Hi i agree voltages are high, but this is basic building block to show other kernel developers how to overclock, it is not official release, unfortunately i havent had the time to thoroughly test this. The clock is not locked as I have tested.
Based off latest kernel from nvidia yes

Okay weird mine can't pass the 2397 Mhz limit. I will try on my girlfriend's Shield Tablet.
By the way, the gain in Dolphin scale very good with frequency. At 2397 Mhz, bring a 16% gain(Dolphin is a dual core app). So 8% up frequency x2 .
In reality, that's mean Mario Kart Double Dash run now at 36 fps in ChampionShip(before running at 31 fps). Haven't really tested others games for now. That's why i wanted to reach 2524 Mhz.

Ok so I'm a complete noob at all of this but I'm trying to get Dolphin running on my Shield Tablet (5.0.1) at decent speeds. I constantly see things about changing the screen resolution to 480p, "overclocking" and other things to get it running somewhat smoothly. Is there a step by step guide to getting this up and running right? What settings, apps etc do I use?

Sort of in the same boat, From what I understand a lot is being worked on in a fork of the app.
from reading the linked forum this seems to be the latest app

a lot of options are not available front he apps settings interface yet and have to be modified in the dolphin-emu\Config"\Dolphin.ini" file

any one able to share there config files here?

Benchmark Table Comparison - 3DMark and Geekbench 4.2

Hello and welcome!
This morning I began wandering the XDA ZUK Z2 forums, looking at all these new threads and posts. I'm really impressed with all the progress for the Z2 that developers have been making lately. So I decided to try a few new ROMs.
I have always found really interesting to test new ROMs, set them up, install everything back and then use the ROM for a few days to see how everything goes... Only to find out that a new feature has been released or a new version of the ROM I'm currently using and the process begins again, it's really cool :victory:
So today I picked a few ROMs, and decided to try them all, run a few benchs and write down the results. At the end I thought I could share the data gathered and perhaps we could get some idea of how these ROMs perform.
So the general process was the next:
Wipe everything but internal.
Flash ROM and ROM alone, no GAPPs, Magisk or MODs.
Wipe Dalvik and Cache (dev recommendation).
Shutdown from recovery, boot, install benchmark apps and restart.
Clear recents and begin benchmarks.
Notes:
TWRP used was latest official version.
Baseband is the latest official baseband for the chinese Z2.
ROM version was the latest as of yesterday.
Kept the phone above 40% battery, so battery charging was needed between ROM flashing from time to time.
Cooled phone between benchmarks, as to prevent throttling from affecting the benchmarks, however didn't add cooling when benchmarking.
Alright then! Let's get down to it!
Data:

SSE: Sling Shot Extreme.
SSE scores: Overall scrore, graphics score, physics score. Ditto for Vulkan.
Geekbench 4 scores: Single core, multi core.
Geekbench 4 COM: Compute benchmark.
Now let's talk a bit about these numbers. As you can see Oreo ROMs get higher scores in both 3DMark and Geekbench benchmarks, with Cosmic getting the higher score in the Sling Shot Extreme OpenGL benchmark and Cypher in the Vulkan variant, although not by much. In Geekbench Jaguar leads with the higher score in both the single core and multi core test. Now look at every Oreo multi core score, it is higher than its Nougat counterpart, I wonder if this is in part because of the drivers or OS optimizations, however I also wonder how this shows, if it show at all, in real world usage.
I would like to note that if I'm not mistaken Jaguar had increased CPU frequencies, not sure about the GPU though, and that could be one factor for the increased scores, however OMNI got really close to Jaguar and again, if I'm not mistaken, Jaguar is based on OMNI. I would like to point that as the day passed the room temperature increased (hot day), so take the temp thresholds with a grain of salt. The battery percentage loss found in the table is that which 3DMark reported in the OpenGL test.
One thing is that even when the numbers varies from ROM to ROM the difference is not that huge (around 12% max in the multi core CPU test), and most importantly... how this translates to real world usage?
So perhaps you noticed the last column, Dolphin. I decided to install the latest Dolphin version and run The Legend of Zelda - Wind Waker intro screen and write down the highest and lowest FPS reported by the emulator. What we find is that the scores do not always reflect into the emulator FPS. Also there is a 'DoT' in almost all ROMs, what does that means? Well DoT stands for slowDown on Touch, yeah it makes no sense but it stuck. When running the emulator if the phone detects no input from the touch screen the FPS slow down by approximately 40%, that's what DoT means, I had to keep touching the screen to get full FPS, only on Citrus this was not the case, and I was getting full FPS with no input whatsoever.
So what all this means? Surely we always like to see higher numbers, I know do. But with time I have found that higher numbers are not necessarily better, or that it does not translate to better performance, battery life or SoT, stability, features, etc., for example in Oreo ROMs I always liked more how colors showed in the screen, even though we have KCAL in Nougat ROMs too. Also I ran these benchmarks only once, so they are not one hundred percent accurate. Usually more runs = more score accuracy, so take these with a grain of salt.
For fun I decided to OC the CPU when using Citrus 3.5, set Adreno boost to high (honestly don't know what it does just that it boosts something related to the GPU I guess haha) and even when the benchmarks didn't improve that much (actually it got a worse multi core CPU score) I got better Dolphin FPS, and that just proves my point.
And that was just one real world test which I think it's heavier on the CPU. I would like to test an intensive GPU game and get some data on that. Also, numbers don't say much when talking about customization and features, so to really feel a ROM you have to test it out yourself.
It would have been awesome if I had have the time to test more ROMs or kernels, I just picked some ROMs from the Telegram group and some here randomly. But! That means that there is more out there for you to try out! As I said in a post this morning: That just means you have a lot of options to choose from and have fun installing, customizing and using the ROMs in your phone.
So yeah, had fun doing this and wanted to share. A HUGE thanks to all the developers out there! Thank you for giving life to our device! :highfive:
EDIT. Please forgive my english, I'm still learning

Great info , thanks :fingers-crossed:

I think the most battery friendly ROM would be stock. However custom ROMs keep improving, so that's awesome. Other than that, this was just an experiment to get some numbers therefore I can't really say about battery.
There are so many factors, like battery drain on light and moderate usage and heavy CPU and/or GPU usage, deep sleep, hpereat, stability, user experiencie, etc.
It is hard to measure these with benchmarks alone.

Fascinating post, thank you for doing this!! I just bought this device for 7k refurb (approx 100$), should easily last a year or more.
Would it be possible to do a run with the Pixel Experience rom? Or is that one similar to the other ones you've already done? Just doing my research on this device and the various roms, its blowing me away how much horsepower exists in this thing for the low price!

I understand and the reason is that I decided to try a batch of ROMs I hadn't tried before. I wanted to try many more, but time didn't allow it. Perhaps sometime close I'll do another run :fingers-crossed:

Very interesting! Thanks for your time.
Im considering to flash jaguar... im now on aex 5.2 but seems that jaguar is smoother and run good. Waiting for new latest builds to test this two and decide.
