So as the title says I stumbled upon the MasterComfig OS Optimization and did most of the stuff listed there as well as a few unrelated performance and boot time changes.
And after starting the game again, I felt a performance boost and an fps increase but at the cost of my aiming,
my mouse feels smoother and slower and I am having a hard time hitting the shots I was hitting an hour ago, it didn't change after a few days either.
Raw input is still on, mouse accel is still off and my sens and dpi didn't change.
Maybe someone knows why did this happen?
