Im not familiar w/that game, but some older games such as;
Beyond Good and Evil for example
Run perfectly fine under 7, but ALWAYS say your graphics are out of date.
For some reason they do not recognize the card,and automatically assume its out of date.
IF this is the case for your game, its safe to ignore it and move on. It will not effect the game.
If its a newer game, chances are you indeed do need to update drivers
and possibly DX
