I have an nvidia 650 ti, an i5-3450 the z77 extreme 4 motherboard and 8 gigs of ram yet a lot of the games i play are still super laggy like Battlefield 3, and even battlefront 2 sometimes. My friend said this could be caused if i didnt have all my motherboard drivers up to date, even the ones i dont use, I was wondering if any one else had an opinion on what could be causing the lag any help would be appreciated.
