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.

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.

For me only pinball hd for tegra works fine... nothing else :/

Tried with guerilla bob thd, and a few other thd games. But chainfire doesn't work with those games.

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.

Another odd thing I noticed, I was only able to oc to 600mhz when I've heard I could oc it to 1000mghz. Is this something to do with my rom?

Overclocking to 1ghz is not possible with optimus one...maximum stable clock speed is 806mhz...it seems u r on stock with root...in that u cannot oc to more than 600mhz...
use any other custom kernel...or simply use any other ROM...

LOL 1gHz on an Optimus One... Haha my O1 gets 806mHz tops!

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'm going to try out this talho rom and hope for the best.

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

One core, smoother

So I have been using GB for a long time, only DAILY use, it means no hardcore games, no incredible features etc. Recently I got bored n decided to set my s2 to only 1 core, and to my surprise, it's got A LOT smoother, also more BATTERY FRIENDLY. I'm sure about that!
I guess this happens only when you're a casual user. But I think you should try, as the benefit is too much

How you set one core ?

How to set? and how much difference in battery?

Most kernels let you do it. Siyah along with Extweaks lets you do it

I don't get the point, how a device could become 'smoother' by disabling one core?

I just have mine set 100Mhz-800Mhz with both cores enabled. Obviously it won't play advanced games well but most 3D games work perfectly fine. Also, there's no lag in the UI, even though the CPU clock is reduced. Additionally, the back of the phone (near the camera) doesn't heat up anymore and the battery life is extended. Honestly, it's worth a shot.

simple becoze samsung didnt do there job right
the way the 2 core work now is 1 core dose it job and the second waits for the first to finish
once the first core finished its job the second core goes into play and the first one wait for the second core to finish befor it start to work again
its the same story in ICS
hope it be fixed in JB
so basicly u have a delay on work
that why 1 core is more effective cuz it dosnt pass jobs to other cores and waist for them to finish

I'm using it now and there is a marked, difference in the, speed and smoothness .I have not notice any slowness in opening apps our browsing I don't do intense 3d gaming so I can't make a comment on that side of usage ....well see how battery usage goes...
Sent from my GT-I9100 using xda app-developers app

Setting one core is very easy on a rooted phone, I guess there's a app to exclusively do that, but I'm using Extweaks here, just set the threshold to enable the 2nd core to 100%, it means the 2nd core wont be actuvated.
It's true that it's much smoother, people, I mean real smoother, I'm not biased or imaginative. For e.g when I open 9gag, a long page and swipe my finger up for e.g. it used to be laggy when the page slows down itself, now that's completely gone! And a lot more. But Im sure this happens only for normal user like me, don't expect u play Asphalt HD and it's smoother!
About the battery, it's just A BIT better, just a bit, maybe about 20' of screen on. I'm really sorry to buy a 2 core phone just to use 1 core now, but see, if it serves your demand better, then why not use it .

I have been messing with my phone a lot, and it's like this: based on what u set, if the cpu threshold is over a number, it will ignite the 2nd core, I think the problem is here, there's something wrong or delay or anything that will cause a lag when the 2nd core join/retreats, although after that with 2 cores it is smooth

Holy sheet, if this is true then it explains all my wonder why it has a lag when I suddenly give the phone a heavy task and vice versa, but this is a stupid way to work, how can't they know that? ??

Just set my CPU hotplug to "second core always off" and what do you know, indeed it did feel smoother.
I'm gonna roll with this for a while and see how it goes.
And that will really stick it to the iSheep that says Android needs fast hardware to run smooth.

Does feel smoother, but the touch responsiveness isn't as good.

As I understand, the operation works like a dual core pc. When the 1st core is loaded say 85% the 2nd core kick in. In this process there should be no lag. 2 cores can handle more information compared to 1 core. This is basic. I maybe wrong but think of it 1 against 2.

Disabling hot plug is a good idea if you're a basic user. For people like me, who uses their phone for playing games, watching "hd" movies, listening music, browsing internet etc. and multi taking all those, the phone becomes unusable. So this guide doesn't apply to all, but it's got a point.

A list of questions

Hello All! I have a somewhat large list of questions that I'm hoping you'll be able to help me figure out!
Here they are:
1. How large of a gain do we see by overclocking the GPU?
2. How large of a gain do we see by overclocking the CPU?
3. Which of the above two creates a larger heat increase?
4. What is "mpdecision" and what does it do?
The fifth question is very specific.
5. When I "supercharge" my phone using Zepplinrox's V6 supercharger, and then finish it with it's sister script the "Ultimate Jar Power tools," I see that the ADJ values don't stick. Why is this? What are ADJ values? Will this prevent me from fully utilizing the Maximum Multitasking Mod?
Thank you for your time patience,
Connor Baker

why would u even want to overclock? this things running a quad core at 1.5 by default. plus those supercharger scripts are meant to speed up slow phones. i don't see what someone could possibly gain by running them on a phone like this.

I know, but I really like to have my phone running at the max, plus I believe that it's needed for the Maximum multitasking mods. It really thrills me to have something faster than my mother's mac in my hand.
Connor Baker

well in that case ill help you the best i can lol... in pretty sure CPU overclock heats up more. GPU overclock can make your graphics glitchy if you go too high. mpdecision lets you shut off your other 3 cores when you don't need them so basically you'll be running single core unless you put your CPU under a heavy load like gaming, which is meant to save battery.
Sent from my Nexus 4 using xda premium

Don't overclock unless you feel you need to, you'll be shortening the lifespan of your device for very little gain, since the n4 already screams as it is.

Is there a way to have individual core Control

Is there a way to have individual core Control clock speeds and governor if possible I'd prefer an app for obvious reasons (easier) I'm on cm10.1 5/9 nightlies
Sent from my Nexus 7 using Tapatalk 2

Some of the rate governors (not all of them) let you select the maximum number of cores allowed to be online. Depends on the kernel, but in principle you can use Trickster Mod. While clocking on the Tegra 3 is quite flexible, I believe it is not possible to have separate G cores operating simultaneously with different clock rates.

That's lame the subject came up because I have it working on my Atrix HD AT&T but I think I'll try another kernel

Extra battery but more speed with a kind of stepping stone per say look at it like this using my dual core 1.5 ghz atrix hd as an example
Sleep one core and you run single core with lots of lag
But with this method you can under clock core 0 1ghz to and change the government to interactive use the second core as something to the n7 companion core take it way down farther let's say 600mhz with on demand or possibly conservative governor. That way the second core would come on in times of lag for a small push to end lag spikes and like I said works on my atrix quite well
Sent from my Nexus 7 using Tapatalk HD

I think I would expect what you are describing to exhibit strange (pathological) behavior unless all of the rate governors are re-coded to collect their heuristics partitioned by processor thread affinity.
Does this also mean the 2nd processor is never off-lined? (They can drain a lot of juice even when underclocked due to static power dissipation issues, so it makes me wonder if the power savings is real)
Is the kernel development work for that device (Atrix HD) described anywhere by the implementer(s)?

A couple I couldn't point you to a definitive answer as I'm not a dev though it's defiantly someplace here on the forums even a kernel to look at

Are you talking about that script-ware by smokin1337? If so, it seems to (try to) work by forcing the second core to be on-line at all times, and then changing rate governors on a per cpu basis, not in the kernel but by continuously writing to each cpu entry in sysfs.
I peeked over in the Atrix HD forum and it seems it doesn't even have any working custom kernels yet...

http://forum.xda-developers.com/showthread.php?p=40253686
That's the only kernel to my knowledge
Sent from my Nexus 7 using Tapatalk HD

@Franzferdinan51
Maybe you could throw me a bone - what exactly is it that you are using on your Atrix HD that does this? (Is it baked in to somebody's ROM, or a separate flashable patch)?
I *did* go searching over in the Atrix HD forum rather extensively.
Downloaded Codex01's "CM10.1PreformanceEnhancements-3.0.1" and looked in there - this doesn't do what you say.
Downloaded tcf38012's popcorn kernel and unpacked it and poked around - it also doesn't do what you say (lots of other tweaks tho).
Found a mention of something similar in posts by skeevydude. Downloaded smokin1337's "CPU Editor" for snapdragon - it was mentioned in passing in the Atrix CM 10.1 thread.
Am I just looking at the wrong things?
Anyway, everything that I've found so far that looks close to what you are describing writes control information to stuff in /sys/devices/system/cpu{/cpu0|/cpu1}/*
For what it is worth, that same (sysfs) stuff does exist in various N7 kernels - for instance, per-cpu entries for min/max frequencies and rate governors in /sys/devices/system/cpu/cpu{0|1|2|3}/cpufreq/.
So, maybe what I said first was wrong. Maybe the right answer should have been "kinda - maybe - sorta". I would have to understand the PLL schemes that different kernels use a lot better than I do to be definitive.
But I am still a bit skeptical that it actually produces the result that it claims - saving battery life by forcing two cores to be online at all times... without also affecting performance. And the part about two independent control loops affecting each other in pathological ways remains open as well (threads running on the other core with a different rate governor affect the measurement of the recent system load averages used by the second rate governor - and vice versa).
It would be useful to have a decent and repeatable way to benchmark interactivity - the first-person reports of "this is really smooth" or "lags badly" are always completely subjective and non-repeatable, so it is hard to know who to really believe when it comes to reports about this stuff.
cheers

Tegra Overclock App - Play Store

Not my app, but I seen this over on the N7 forums and thought I might share. I haven't personally tried it but seems pretty cool. It might be able to get a few more FPS out of some of the stuff the Ouya is doing.
Tegra OverClock
I don't know how you'd get it installed on the Ouya without having to backup and restore the APK by sideloading.
It seems it was just released today.

It appears to use drm tied to Google framework.

Well after doing some research it looks like (Assuming you're rooted with custom ROM, cwm recovery, Google Apps enabled etc.) We can "safely" overclock the GPU.
I used Google translate and found the following Spanish user said, "Tegra overclock (no Tegrak): Default uya the gpu of 200mhz and can come to no problem climbing to 520 (more crashes) and force the 4 cores to stay on. It is quite noticeable in some ways, the vice city to the fullest without almost pulls, n64 emus greatly improved the framerate but less so in the benchmarks. The temperature in my case (I have it out of the box) is no problem. http://www44.zippyshare.com/v/71430637/file.html

He was simply quoting a Spanish website regarding Tegra3 GPU clock - this has nothing to do with the O/C app. IF the app is optimized for Ouya, it won't be Spanish only of course.

It is working fine for me on 519r2. If you don't mess with the CPU speed, which there is really no reason to, there shouldn't be any noticeable increase in heat. I just have the GPU set to 520 and the FPS locked at 60. It has definitely made games I considered previously unplayable, playable.

In my case, even with "Set at boot time" enabled, the settings are not sticking. I have to do it every time I power on the box - which becomes a bit tedious. Same goes for not being able to wake the Ouya from the controller.
I checked with No-frills CPU Control to see the CPU % use vs different governors and I found (same as on my N4) that "interactive" seems to be the better one.
