Is because no frame limit so your pc run max power, you may be playing this game at 3000fps or so, you have to limit your fps to fix this. I use rivatuner but hopefully they allow us to select fps when release.Why does this game make my pc fans rattle so much? Literally is a 871MB size and it's not like my pc can't handle this size of a game. I would appreciate if someone can tell me why.
