FastMathFabric
FastMathFabric replicates OptiFine's Fast Math feature as a Fabric mod. It is incompatible with Lithium and OptiFabric.
Note: the "SmallAngleMath" file is even more cursed - instead of OptiFine's Fast Math, it replaces the math with the small-angle approximation (sin x = x, cos x = 1)
