[Category] FastMath option makes AntiCheat false flag.

[Tecnio]

Description of Issue

(FOR PEOPLE THAT SAY 99.99 IS UNECESSARY THATS NOT THE POINT! A GAME AFFECTING GAMEPLAY IS NOT FINE AND ANY GAMEPLAY AFFECING MODIFICATION IS AN UNFAIR ADVANTAGE AND FLAGS ANTICHEATS) Basically when I or any other player uses fast math the different sin and cos table screws up my 99.99999% horizontal velocity check as Minecraft uses the MathHelper class which optifine edits while doing and this causes a 1E-4 offset from predicted on my check and for my first attempt at a prediction engine.

I saw this module effecting a few more anticheat developers complete prediction engine as well as my prediction and velocity check. https://artemis.ac https://grim.ac

If this was fixed it would make our job very much easier, and prevent people from having an unfair advantage.
