I have same issue. It's so bad that when I'm looking at the ground and looking left and right really fast I can watch the light from my monitor create a strobe effect on my walls. Disabling AA, and lowering resolution to from 1440 to 1080 helped, but it's still there. It's the only reason I quit playing 7d2d and I really wanna give the new update a go, but it's not fun to play like this.
