GLTools (originally by zhuowei and later maintained by Lin Jinbin / iHe1l in community versions) addresses this by hooking the OpenGL ES library ( libGLESv2.so or libGLESv1_CM.so ) and modifying parameters at runtime. The Magisk module version replaces system graphics libraries with a wrapper that injects the GLTools hooking engine without modifying /system directly, preserving system integrity.
With the decline of Xposed (due to ART changes, SELinux, and SafetyNet), and the rise of as the de facto root solution, developers ported GLTools’ core libgltools.so into a Magisk module that uses zygote injection via Magisk’s replace system and libs overlay.
: A brief summary of what the module does. For GLTools , it is important to mention "systemless" to highlight that it doesn't break OTA updates. Template Structure gltools magisk module
Take full control over your refresh rates. You can unlock maximum frame rates beyond system restrictions or cap your FPS to prevent thermal throttling and save battery life. It also includes an accurate, real-time on-screen FPS counter. 4. Texture Decompression and Recompression
Lower the internal rendering resolution of games to boost FPS on lower-end hardware. GLTools (originally by zhuowei and later maintained by
Reduce the internal resolution of a game to boost FPS without changing your device's overall screen resolution.
That said, GLTools can still be useful for: : A brief summary of what the module does
The is a powerful custom OpenGLES driver optimizer that allows users to trick demanding games into thinking their device sports a flagship processor, unlocking hidden graphic settings and boosting frame rates. What is GLTools Magisk Module?
You can force games to disable Anti-Aliasing entirely to maximize speed, or force-enable high-end MSAA to smooth out jagged edges in older games that lack built-in graphic menus. Prerequisites for Installation
