A:AnswerDepends on the settings. It may be a simple looking game but you still need some power under the hood to run in at it's highest settings, it should still be able to run it though.
A:AnswerMaybe witcher 2 but probably not 3. These kind of games require more ram and video memory than this computer offers, plus it may overheat. I would suggest spending a little more and getting to comfortably play these and other games.
