Asus 4870 x2 Tri Fan Problem

I have one of these great cards and am having a problem, that I hope someone out there can help with. Card works flawlessly on Oblivion, Fallout 3, Crysis, GOW. Sadly on Far Cry 2 and the new Batman Arkham the load last load screen persists on screen. The game plays in the background with the ghost image of the load screen remaining on screen. This problem is the same for all quality settings, AA, and resolutions. I think I've tried activating and closing every possible feature. The load screen just won't leave. The manufacturer has been non responsive, Can anyone help?
