Purchased a XFX 520M 7900GT from Scan. Got it and tried Tomb Raider on it and it was rendering all the "shiny" objects in blue. Got the patch for 1.1, it has fixed most problems on the game but not all.
Next - I tried Pariah, when ever a granade is thrown or something that blows up the screen just flashed gray and you cannot see a thing - it's unplayable. Also this has been patched to 1.03 (latest)
Next - Rollercoaster Tycoon 3 - Golden items such as sand are VERY bright and take all over the screen and you cannot see a thing. I have turned down settings and nothing seems to work.
I have tried the Nvidia BETA drivers 88.94 and the newest (released May 23rd) 91.28 both have no inpact only a new control panel.
