I've tried to play unreal Tournament but It didn't work correctly. I get some kind of plane levels on my screen. I've downloaded all the drivers from the official Elsa site and also tried the drivers from Nvidia. But I still get the strange 1 color (grey, black) levels on my screen. I downloaded the Unreal Tournament patch 4.2 too. But that didn't work either. Does somebody knows what is the problem and can somebody help me solving this?
