3D driver optimisations - Galaxy S I9000 General

Hello every genius !!
Can someone add 3D driver optimisations in their fabulous kernel / rom like cyanogen mod7?
In cyanogen mod we can notice a real boost performance in 3d applications. So why not include the cyanogen 3d driver in next rom or kernel ?
Thank you all !

I'll quote my post from another topic
Guys, look at that:
http://glbenchmark.com/subtest_results_of_device.jsp?D=Google+Nexus+S&id=405
There are 12 tests of Nexus S in GLBenchmark, and 11 of them are below 2400 points (more or less like our SGS), but the most recent one (uploaded at 2011.02.11) scored 3025 points, more than Tegra 2. This result's is made by someone from GLBenchmark, and shows at "GLBenchmark team tested" page of the results. How is that possible?

So, according to this benchmark, the performance of Nexus S'ses SGX540 increased dramatically somehow. And according to this article,
LG's software build also uses a newer version of Imagination Technologies' driver (1.6 instead of 1.5)

So, maybe, in the latest update (2.3.2, or whatever) Nexus S got this new 1.6 GPU driver with increased up to 30% performance?

Now this is getting interesting!
any more info about this ?

fake?
I think ots a fake or it was a special rom, i use darys rom with voodoo and have 2537

But wich driver the Cyanogen team use in their cyanogen mod7 ?
Their 3d driver score in quadrant pro is very impresive, nearly 30 to 40% more than stock froyo 2.2 rom.
I will try to ask the cyanogen team.
Kepp in touch

// oh your right
Well.. This really looks interesting.

Now this is interesting

Looking forward to this

Surprised someone with a little more knowledge hasn't commented on this yet. Hopefully we'll have an answer soon

In the meantime -> report here if the sources (I mean precompiled module, which will be inside the package) are online

What is your quadrant GPU score in CM? On JS5 2.2.1 i have 2d:293; 3d:879. Are CM scores really better?

SGX540 is much better GPU than the one used in Tegra 2.
So I guess these results are caused by the newer driver version (1.6) released by IT.

with mitra rom i have these score on quadran advanced:
overclocked to 1.3ghz (on set cpu min and max @1.3)
total score 3702
at stock 1ghz (on set cpu min and max @1ghz)
total score 2865
good score for me with this rom.
i thing that the driver are updated...

hey flipz how about another benchmark

how bout another benchmark for all these latest and greatest roms that claim to be too fast for class. so we know the truth once again

wow awesome quick response too... i knew i liked u for some reason
Won't hardware benchmarks always be the same between all ROMs?
Is there a way to objectively benchmark resource management? Speed of the interface, opening apps etc.
i didnt see the last one but id like to see benchmarks like on te gsm roms
http://forum.xda-developers.com/showthread.php?t=656818
Also the following for benchmarking:
For 3D Performance
* Qualcomm's "NeoCore" 1.9.18 - Measured in FPS
For 2D Performance
* Softweg's "Benchmark" 1.03 - Measured by an internal score
* "Lag test" - Originally to measure 2D performance for Motorola Droid users. Measured in FPS
For CPU Performance
* Linpack for Android - Measured in MFLOPS
All of the tests mean: The higher, the better.
The method of testing was the usual flashing, a couple of reboots to make sure every caching necessary was done and the average of 3 benchmark of each test.

And it's also 1.5 which makes it irrelevant for these tests.
Someone should come out with a rom, with JIT enabled.
Then they can claim they have the fastest rom.
I had it running on dc 2.7.2 without any problems.. Just cant use anything HTC, like lockscreen or sense.
But nexus or helix launcher and beautiful widgets, everything is normal again.
JIT is too buggy still, im looking foward to playing with compcache when someone gets 2.6.29 source working

I agree its not perfect.. But i can use it on my daily rom and run every app I would on a normal day without an issue.
Before dc 2.06 came out, i ran it on dc 2.05 for 3 days straight.'
I dont use bluetooth or some other random things. So it would probably start 101 problems for some people.. Like theres not enough already.

Benchmark Tests on Legend 2.1 vs 2.2

Hi All,
Updated my missus's Legend to 2.2 today and ran a Quadrant Benchmark test on it..
best of 3 was 903 (avg is about 860)..
What are you getting on 2.1... and what sort of scores are you getting on the custom ROM's out there?
Post your scores stating which ROM you're running..
Clean Eclair, 2.1 = 4XX-5XX
Azure, 2.2 = 8XX-9XX
Cyanogenmod RC2, 2.2.1 = 8XX-9XX
Never benchmark a Sense ROM before so I cannot provide such information.
Best of 3 was 365 on unbranded 2.1 update 1

I'm sorry Sir, but are you ****ing-kidding-me? With almost stock 2.1 i had ~380. With azure 1.0.x now i have ~460.
I have not programmed anything in android yet, but I know programming java for some years and I think that I can tell you why those spectacular benchmarks doesn't apply in most games.
The improvements have been made in the dalvik virtual machine, which is responsible for executing the java code of the applications.
But if programmes want more performance, they can write part of the program directly in native code, developed in C or C++. This code cannot be optimized (more), thus applicacions using JNI massively don't see any improvement.
I suppose many games should be using JNI because of the advantages in performance, so they're already 'optimized'.
Please, correct me if I'm wrong

Raja, the avarage Azure scores are 4XX because JIT is actually disabled in that rom, even though the option present and checked.

Sorry my bad.
Seems like JIT was disabled only until Azure 0.6.
However I can confirm that my Azure 1.0.1 quadrant score was 4XX (which is kind of low...), and as I now have 1095 with CM6.1 I don't think theres a problem with my legend's performance.
Sorry for the newbie question, but.. how do I run a Quadrant Benchmark ?
I know these numbers refer to the performance, and that the 2.2 scores a lot better, but in actual everyday usage - battery life, speed etc. what does this practically mean?

Install Quadrant and run it. Well, technically it is just numbers. But most of the benchmarkers do admit feeling the difference between lower and higher scores. Some say those are placebo effect, but meh. I don't buy that ****.

[OC] Tegrak Overclock v0.2.0.1

Hi Captivators!
Let me introduce a tool that helps to improve performance of your phone!
NEED ROOT!
Overclock can be harm to your hardware.
Use at your own risk.
I made a overclocking application for Samsung GalaxyS family.
It's designed to make overclock very easy on stock kernel and custom kernels (almost, not CM7, it has its own way)
Only needs to click 3 times to do it.
I know here is not app category, but based on kernel module.
so I chose "Development" category.
If I'm wrong, please move my thread to correct position.
Working perfectly on GalaxyS Froyo. already proved by many people.
I'm waiting Gingerbread for my phone (SHW-M110S).
App will support Gingerbread after I got it. Hey Samsung, give it to me!!!!
My wish is that all of GalaxyS users install this application on their phone... over 10 million..
But I know. It's just a dream.

The maximum frequency that I found on my phone,
1.15 GHz, 1.25 V (stock voltage)
I experienced faster web surfing, more quadrant score, better Linpack result and more..
Hey, who don't want to make phone faster?
You can find a free version app in Android Market.
If you like it you can also buy ultimate version to help me (think as a donation ver)
UV(under voltage) and OV(over voltage) controls are only available at Ultimate version.
Sorry for that but I believe Free version is quite enough for most of you!
@1.43 Ghz, 1.375V + ext4 = quadrant score 2250, and fried my hands
Enjoy your enhanced phone with my application!

yes this app loads a kernel module much like voodoo control plus does. it adds overclock to any kernel instantly. unfortunately for the developer most of us have a favorite overclock kernel. but this will work for adding overclock to kb1 non overclock kernels that some members prefer to use for call quality reasons, and for people that love the stability of speedmod but want to experiment with faster clock speeds

onix is speedmod with OC/UV
EDIT: im just curious, ive traditionally undervolted my phone to increase battery life, what would be the purpose of increasing the voltage, seems as though it would be counter productive?
Well this is interesting. A good app for anyone who remains on stock and dosent want to load a custom rom but would like a little extra horsepower. The small percentage that people here make up may or may not use it, but to the rest of the world that is on stock, this could be really nice for them.

that is a gross over simplification. i believe onix has a lower kernel hz for battery life and additional patches though i never cared to keep track of specifically what features each kernel has.
also the ulk menu on speedmod actually works on all the options including jfs unlike onix
maybe you will have better luck in the epic and fascinate sections where there is no froyo source code so they have to choose between 2.1 overclocked and 2.2
Any chance to get this on 2.3.3?

Decreasing voltage increases battery life (obviously less juice = lasts longer) but also makes your phone less stable. The inverse holds true to a point. For every phone at every cpu speed, there is a range of voltages where your processor doesn't lock up and die instantaneously. Too much voltage makes it die, too little makes it shut off.
In the range where it works, however, the lower end is better for battery life, but if it's doing something towards the upper end of the freq range, it might still die, but the upper end of the voltage spectrum is pretty much good to go.
cant overclock my cappy at all raise it to 1.2ghz without any voltage change and
it says i need the full version...
whats the point in OC app that you cant use it?

Chainfire3D on Optimus One

The Optimus One has the adreno 200 GPU which supports OpenGL ES 2.0 and meets the requirements for Chainfire3D. I have it running on my Optimus T with 2.2 and haven't noticed anything different when configuring the default settings. Nightmode works, but that's just about it.
http://forum.xda-developers.com/showthread.php?t=1087427
Warning: This replaces (from my understanding of the thread) an existing driver with a new one. It requires root.
I would like to hear back experiences from others who have an Optimus one and tried Chainfire3D.
It also requires a 1 ghz+ cpu. Try running a tegra game to see if it works. Don't know if they will even start... HDPI res required.

Tegra Zone doesn't render properly in HVGA but the screen resolution is not entirely the problem. Installing a game from it crashes the device, probably because it was never made to work with ARM11 chipsets.
Maybe it is/will be useful for something we don't know yet.

Problem with Chainfire
I am using an Optimus one Myself and attempted installing this but not only did it fail to install I've tried uninstalling and reinstalling and now it won't even open upthe app to allow the attempt of the installation of the codec. (basically I attempt to launch it, it fails goes back to menu, this first happened when I was able to launch the program and attempt to install the codec) Now my best guess if I had any is It's incorrect ROM or something. I'm not entirely sure I'm still getting used to this phone. Already rooted it and broken once thus fixing/reflashing. So I've learned a few things. But if someone better then me and I'm sure there are lots of you here could just point me in the right direction I'd be very happy person indeed. Also, If I'm posting in the wrong section I apologize I really suck at this forum thing.

I can run 864MHz on my phone and combined with the correct settings on chainfire 3d u can definitely notice a difference in gaming performance
Would the fact that Chainfire 3d is now not even booting also have something to with the fact that I'm running a stock ROM and cannot overclock passed 600?

I figured it all out. simple reading errors on my part as it were going through tutorials and whatnot. either way I got chainfire working just working on download GTa3 to see how it performs.
It worked for me a while ago on CM7 and oxygen, it doesn't need 1GHz+ and is no risk, reflashing the ROM replaces it
Just give it a go, but you need opengles line in build.prop

HTC Desire Z vs U8800 2D performance

Is it just u8800's drivers that make its 2D performance 'sluggish' compared to Desire Z (they both have pretty much the same HW and both oc'd @ 1,5GHz (same Miui 2.1.20 2.3.5, same ondemand governor).
Just wondering 'cause you can see the difference IRL (Desire Z's browser has a lot smoother scrolling and the 2D seems snappier otherwise too).
