Increase the DPI setting on your mouse.Never had any issues regarding mouse acceleration, and I have enhanced pointer precision on.
My mouse never behaved like it was shown in the video, or maybe it's so low I never felt it. (Edit: just used to it)
Anyway, tried disabling the pointer option and my eyes kinda of hurt now.
Edit: Tried the 6 notch + pointer off.
And it's soo damn slow, I have to make gigantic movements to hit the edges of the screen. Daniel-San car washing movements.
How the heck can I turn fast while playing TF2 ? I will end up karate-chopping my PC to the ground.
