Iris & Oculus Flywheel Compat Mod (1.21.1, 1.20.1) – Enable Flywheel's Optimization
Flywheel will disable its optimizations when you use shaderpack. Iris & Oculus Flywheel Compat Mod forces Flywheel’s optimizations to be enabled. For those using shaderpack and mods depend on Flywheel, this mod can significantly improve fps. If you don’t use shaderpack, this mod has no effect. Because Flywheel’s optimizations are enabled by default.
