Ever since owning this sapphire 5850 extreme since buying it from OcUK in april, when I play need for speed shift 2, I get occassional washing out of colours in the game. Like at the moment, the race circuit and car I'm loading has faded bodywork, dull looking grass, faded colours on the racing line. When I minimise the game and then maximise it again, it's back to normal with nice vibrant colours. I've not heard of anyone else with this problem in the game, although I know the game is full of bugs, so could I have a faulty card and is there a way to properly test it?
