Hello! PC noob here just having a question. I´m having lag issue and also a somewhat "flickering light" issue when in hte open world. I have a good graphic card (580 geforce) and about 12 gb ram but only 2,8 ghz CPU. I get some annoying lag, mostly in open world. The same kind almost wether I play medium, high or ultra. I not play on high with skyboost, latest geforce drivers, and so on and the game is very much playable but my question is, how can I improve the lag without having to upgrade the cpu?? Is there one setting that is very cpu heavy that I can just lower?= Is it possible to somehow make the game use more RAM (I´ve read somethign about it while searching the internet) or do you guys have any other ideas?? Sorry for really bad english
