Well i have a XFX 7970. I found that the newest video card drivers 13.8 did not work good with 14. the 13.6 beta drivers work nicely. Just google 13.6 beta drivers if you have a AMD / ATI card. Ive no clue about Nvidia cards though. Sadly when 13.8 was not giving me a black screen and random FPS on 2 then the game crashes i got very nice FPS. Better then with the 13.6 drivers, but no crashing haha
