Need help with fps prob. :x

Been trying few things to fix it, but still probs with it.

Most maps running stable 125fps.

Radar: Wider view spots. 75~125fps
Grush: Quite same as Radar, bigger areas only. 95~125fps.
Adler: Mostly only gun controls area. 90~125fps.

Tried to tweak config a bit to give fps boost, but didn't rly do much lol.
According PC specs, should be able to run 125fps stable every map imo.
3o3 or 12v12 public, didn't had almost any difference in these maps.

I dno really what else to try. :x

Any advice/solutions/suggestions?

I also had though about.
Can it be server problem only? (Seemed to be quite fine some servers I've played)
Need some more fps boost from config?

Thanks in advance, hoping to get something more then only flame. :D
