Hi back to PC gaming after a long time away. I installed DX9 to play Unreal 2 with my 9700 Pro. Looks fantastic with max settings. However, I forgot that you can't roll back DX and didn't take a snapshot .... Now Mafia won't play. I know it's an oldish game but is there anything I can do - it does run but very screwed up. Shall I try reinstalling it under DX9 (DX8 when unitially installed it) or shall I return it?
