My average FPS was 180-220 but its not 70-110 and often drops to 40 but idk why.

Video Settings (Never changed them)
Resolution: 4x3 1280x1024
Display Mode: Fullscreen
Advanced Video Options: All low & everything disabled

The weird thing is that I got a better FPS as CT around 120+ but as T its only 70- 110,
I also get often some FPS drops near smokes

EDIT: Did the Test and my FPS drops to 27 when being in the Smokes.
Average FPS 68,47
