my specs - intel i3 4005U @1.7 ghz - ram 6gb - windows 10 64 bit - Nvidia 840M - 144hz monitor fps is around 40-50 , confused when my friend with lower spec computer is having around 80 fps on max setting ,when im just having 40-50 on any settings. Even if i lower my dota 2 graphic settings it stays around 40-50 and sometimes even drops to 30 when fight goes on. Im even running 32bit Dota 2 and it doesnt really change anything.Some ideas why is that and how to fix it?
