hi everybody i have a problem , recenlty upgraded to a gtx 950 from a hd 7770 , with a phenom II x4 3.10ghz , very good improvemente over all , exept in dota 2 im kinda caped to 45fps the same as the hd 7770 was , i dont know why i check with msi afterburner and the cpu usages never goes more than 81% , and gpu usage about 15-35% , while in other games like bf3 i got both to 100% and constant 60 fps , so what would be limiting me ?
