[...] Okay, just my 2 cents: I think the result 1100 fps is okay with 16 bit of Color, with 24 bit 528 fps is also okay, I don`t think, there` s more performance in this card... Or did you get 1100 fps with 24 bit? I am using debian unstable, together with XFfree 4.3 from experimental and Daenzer XFree Package on a vanilla kernel 2.6.1. Greetings Peter Frühberger
