I am currently playing the PC version of Prototype 2 and after playing it for one hour, I think that this is one of the worst ported game that I have played. The first thing that will cause the problem is the lack of support for many graphic cards. I am using Zotac GeForce GTX 680 and my graphic card is not supported by the graphic card. I installed the game and started it. The display went back with audio playing in background. Downgrading the graphic drivers helped me get back the video. Did anyone else too found that Prototype 2 is badly ported for PC?
