RTSSFix is a tiny Fabric mod that prevents Minecraft from crashing when RivaTuner Statistics Server (RTSS) is running alongside the game.
The Problem
RTSS hooks into Minecraft's GPU context and interferes with its OpenGL timer queries. This causes Minecraft to crash with: IllegalStateException: GlTimerQuery is closed
This happens because RTSS closes GpuQuery objects that Minecraft is still trying to read from, causing the game to throw an unhandled exception and crash during frame rendering.
The Fix
RTSSFix injects into TimerQuery.FrameProfile and safely catches the exception. Instead of crashing, the mod skips the frame timing result for that tick and logs a warning. You keep your FPS overlay, Minecraft keeps running.
