Clear Gpu Cache
by StarChen
Clear GPU Cache is a client-side optimization mod that clears the graphics card's cached data to fix certain rendering errors.
What it does
The mod addresses rendering problems caused by stale GPU cache data. Clearing that cache resolves some visual faults, and the author reports that it fixed issues seen with the zink renderer, particularly on less capable hardware such as cell phones. The effect is comparable to what OptiFine's Smooth FPS option aims for, without the same compatibility conflicts.
Clear GPU Cache runs on Forge and NeoForge only, and only the client needs it, so servers do not have to install anything. Files are published for 15 release versions 1.19.2 – 1.21.11, with 1.0.1 for 1.20.1 and 1.0.2 for 1.21.11 as the latest Forge and NeoForge builds. The code is released under the MIT License and is open source.
The author notes that using the mod can cause a slight drop in frame rate. The author also states that the mod was created to fix an earlier problem and is no longer updated or ported to later Minecraft versions.
