AnimFix

Animated textures are normally uploaded to the graphics card one at a time, and that overhead grows quickly once a game has hundreds or even thousands of them, producing stutter. AnimFix avoids this by batching the animated textures into a single large texture that is uploaded in one pass. The batching limit can be set in the mod's config file, and turning the fix off is also possible for players who prefer the original behavior. The mixin-based approach was built to address the problem in games where OptiFine or Animated Terrain are not the answer.

The change adds a small amount of extra video memory on modern hardware, a cost the author describes as negligible next to the saved uploads. AnimFix runs on the client only, so a server does not need it and players can join a server without installing anything. It depends on FalsePatternLib, which must be installed alongside it, and it can use SpongeMixins 1.7.10 as an optional dependency.
