kevin89, the AMD/Ati drivers are generally poorly implemented in Linux and suffer from many problems. In your case, it all depends on the model of your card and the driver you're using (the one from your distro or the official from the Ati site ?). But I insist on the fact that the current beta session of GW2 is more a CPU stress test. In other words, whatever your GPU is, the most important part for good framerates is the CPU.
