OpenFG is an interpolated frame generation module that artificially multiplies in-game FPS for Android devices. Utilizing Zygisk, it forces frame doubling in supported OpenGL ES and Vulkan titles, requiring a companion app to toggle the effect on a per-game basis.

My Experience

I've been running this on my daily driver with a Snapdragon chip, and the hardware rendering handles heavy emulators like Winlator surprisingly well. You'll notice an immediate difference once that little on-screen FPS counter pops up, but keep in mind that I strongly avoid using it in competitive shooters like CODM due to the anti-cheat ban risks.

Core Features

Hardware-level interpolation ensures Snapdragon devices get stable frame multiplying, though Mediatek users are currently stuck with software rendering.
Track performance metrics directly on your screen by enabling the extended overlay to watch GPU temps and RAM usage while playing.
HDR display support pushes past normal screen whites, giving you dedicated sliders for highlight boost and shadow depth on compatible panels.
Emulator compatibility includes popular setups like PPSSPP and GameNative, but don't try it on Cemu just yet.

Support & Requirements

Android Version: Android 10 or newer (Android 11+ highly recommended).
Root Type: Magisk or KernelSU.
Dependencies: Zygisk must be enabled.
Hardware: arm64 or arm32 CPUs; Games must use OpenGL ES 3.0+ or Vulkan.

How to Install

Flash the OpenFG Flashable Zip file through your Magisk or KernelSU app, then reboot your device.
Install the companion OpenFG Apk like a normal application.
Open the app, toggle the mod on for your specific offline games, and launch the game to trigger the FPS counter.
