GLTools

GLTools is a custom OpenGL ES driver (proxy), that is compatible with any known OpenGL ES-compatible GPU + ARM or x86 processor. If you still don’t understand, what this app is, the closest known analog is Chainfire3D. Note that GLTools is currently OpenGL ES-only and doesn’t support Vulkan games.

Features:
★ Change GPU name and enjoy enhanced graphics even on a no-name low-end GPU
★ Change RAM and CPU info
★ Take full control over textures: now you can decompress/recompress them (even if your GPU doesn’t support that texture format) and resize. Note that decompression feature is available only if you install a plugin (internet is required to do that)
★ Optimize shaders on-the-fly for optimal performance (the same optimizer is used in Unity3D engine by default)
★ Change resolution and rendering bitness in any app, even if it doesn’t support that by default
★ Enable MSAA or CSAA in any app to improve graphics quality (make sure that your GPU supports that)
★ Measure gained performance with a nice onscreen FPS counter (or you can output FPS information to Logcat if you are a pro)
★ Launch old games on newer Android versions with expert options

GLTools is 100% safe if you have a custom recovery installed (and you didn’t disable backup in GLTools install dialog), if you find it non-working, you can just flash uninstall_gltools.zip in recovery and email me with details (or request a refund). If you don’t have one, it is not safe, just like any other system-related tool, make sure that you are able to recover your firmware in case of any problems.
