Hi I recently installed windows 7 64x on my computer after having windows Vista 64x for 2 years. However there is one problem, It seems i only use about 50 % of my CPU capacity. I discovered the problem when I tried playing Crysis, Which I never have had any problem playing with Vista. The game was extremely slow and it was then I saw that the CPU usage only was at 50 % max. So I was wondering if maybe I should install something to increase the compatibility between the hardware and windows 7 perhaps. So if anyone have any idea of what I might need to do, Please Help!
