Featured on XDA Portal: Disable CPU Rendering on Devices with the Adreno 200

I started this thread over at the LG-VM670 forums at Android Central. I thought maybe it was about time I share it over here on XDA since it's a pretty great tweak and it works without any added issues.

But keep in mind, if your phone doesn't have adreno200 gpu drivers, this won't work and could probably cause an endless bootloop. Now that that's covered, read up and do this carefully, this will not work on every device and is only meant for adreno200. I may have another tweak up my sleeve, but I need a device with something other than adreno200, such as tegra, to test it out on, which I don't have at the moment. Anyway, this worked out quite well for the Optimus V users, I believe it works on Xperia devices as well and it's been confirmed to work on Galaxy SIII. I'll try my very best to keep this thread updated, I don't have a ton of devices to test this on so I'd really appreciate some feedback so I can update the main post and list whatever devices this tweak works with (nobody wants a endless bootloop, so let's inform each other) oh and before I forget.. MAKE A NANDROID BACKUP!! Just in case :)

I found this tweak while trying to look for a loopy smothness tweak made for ICS, but I ended up finding something better than loopy smoothness, a guide to disable CPU rendering. With this tweak you can take full advantage of your device's GPU. In other words you disable software rendering and enable hardware rendering instead (correct me if I'm wrong).

Original thread where I found the tweak: [TWEAK] ICS Specific Tweaks of XPERIA MOD ROM

If you end up adding this tweak into a custom rom you are sharing, please don't forget to give credit for it. You can thank me and mrg666 for it :)

Confirmed working on:

- BobZhome CM9 [VM670]
- quattrimus CM9 [VM670]
- mrg666 MiRaGe IHO [VM670]
- BobZhome IHO [VM670]
- Galaxy SIII
- Xperia devices
- any device with working adreno200 drivers (in this case my LG myTouch 4G is a good example, it worked marvelously and more noticeably on this device)

It should work on any rom, just as long as it has adreno200. By downloading CPU-Z from Play Store you can tell what GPU your device is running.

What might you benefit from? So far this is what I noticed.

- performance boost
- speed boost
- increased responsiveness
- better audio quality
- apps such as Facebook that would become slow and unresponsive are suddenly blazing fast

I forgot to mention this before, I recommend you use Root Explorer or another file browser that has root support to install the tweak. Also set the permission to rw-r--r-- for the egl.cfg file.

Disable CPU Rendering

It removes the entire soft-rendering pathway, hence good performance.

Download the attachment and put it under system/lib/egl and delete libGLES_android.so from egl folder.

That's all.

P.S. It's flashable via CWM recovery now with the eglpatch, it just got easier. But if you would like to do it manually for whatever reason, this guide will still remain here.

I didn't develop adreno200 drivers, this tweak is a simple change to the egl.conf file, I came across it and tested it with my LG Optimus V and my LG myTouch 4G both on GB and ICS roms for both devices and it works and I'm not entirely sure about this but it should work on some other devices. I'm not responsible for anything that goes wrong with your device, you know the risks of flashing files to root. Make a backup first.

Enjoy :D​
