I here by recommend this game to all linux gamers, its the first full graphics game that has been released in a long that that has just worked, with a crosstie attachment to crossover games this game would get a gold.
The games runs no matter what i throw at it.
the best performance however comes when you turn anti-aliasing to none and shadows, the higher those two go the less fps you will get.
however you can set those to none and have the rest set to ultra and still get 30fps.
The only problem this game seems to have is the patching process and what apps to have installed with crosstie.
The only problem i see that may arise is if rift is shipped with some kind of anti hacking software like aion did,
