It's a 9800 pro, and you can't get 3d acceleration without the fglrx drivers.
glxgears may not be accurate, but I think that when the open source drivers give you 100fps and fglrx gives you 6000fps, that's nothing to sneeze at.
Besides, how else am I supposed to play AlienArena, or any other 3d game?
My post wasn't for help, it was a suggestion, and that is to implement better hardware detection. If freespire can do it, then sabayon can do it.
