The games I've tested so far are Need for Speed: Most Wanted, Need for Speed: World, and TrackMania 2: Stadium.
I can get the games to install and run, however the rendering of the games are broken.
The NFS games appear to be almost-grey-scale, however they don't seem to render any 2D elements such as the HUD and main menus.
In TrackMania 2: Stadium, the clouds in the main-menu are broken and so is the menu text, so I can't really get in-game.
All the games can run with the xorg drivers, however they won't even start with the fglrx drivers.
However, now I can't start TrackMania 2 with or without fglrx.
Note: I am a very new linux user.

Hopefully someone can help with this.
Thanks.
