I have here a 120hz monitor , but I cant find a way of playing the game using high hz , when it comes to competitive shooting games , I really want to be able to have higher refresh rates

just enable vsync it runs at your default rez i have 120 also and its fine caps at 120FPS

120hz and 3d. you need serious graphic power. don't expect if you have higher frequency doesn't mean higher FPS.

He never said anything about 3d
and who cares about FPS you get 120 refresh rate and yes its very noticeable
and yes when you have 120hz monitor with vsync on it caps at 120FPS instead of 60

edit i think i misunderstood you ..ignore

v-sync locks FPS at maximum monitor refresh rate. so its kinda helpful sometime ... specially when flickering at high FPS

Surprisingly v-sync doesn't cause input lag in this game. So awesome.
