A performance Mod Defualt keybind:- 0
I recommend using Chroma HUD 3.0(lite) for hud
-Xmx2G -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:-UseAdaptiveSizePolicy -Xmn512M
Replace the 2 in -Xmx2G with half the size or your ram. For example:- If u have 8gb ram then put -Xmx4G instead of -Xmx2G
Do not use this mod with a mod named FoamFix, these mods together somehow lower the fps by a great amount
