Wow this actually significantly improved my fps, thanks for the tip mate!
Doesn´t Vsync limit the fps to the maximum hz of the monitor? I mean if your graphics card can create more fps than the monitor can display, switching off vsync will not make the monitor show the extra fps...
So you looking for a Mentor. there was a Mentor Mentee program several times in the past, dunno its current situation. I suggest to play 1v1 automatch for now
