Problem on FPS with new PC

Hi there.
Iv got a new problem. It seems that my FPS of Cod4 has been locked at 90-91 constantly.
Does anyone know why?
:dumb:

Have you tried setting the max fps? The game may just be locked on 90. Open the console, and put /com_maxfps, then put whatever value you want, but I’d recommend don’t go over 333

I know about cod mw3… If you want then ask me.

try to use any best fps unlocker

Thanks a lot, iv checked the console, it has been put on 85…
My card is gtx1080 and the screen has 120Hz, its better to set the FPS to max to 333, or set to 120?
