Tremendous work, I was expecting the Nouveau driver before the Avivo one, but perhaps the ATI one is the most urgently needed of course ;-).
So much for bashing fglrx drivers, they are after all not that bad as much they are cursed for . Yes, it gives 50% performance of the hardware's capability, but it more or less works stable ;-). Aside, its not just Linux, ATI's performance in OSX is equally horrible . My sister has a iMac with a x1600, on which doom3 @640x480 gives about 50 fps in OSX, a little better in linux (55fps or so, and a little smoother too - it feels like fps is capped or something ;-) and 120 fps in windows xp. I wonder if iMac users with ati cards have ever bothered cribbing .
Meanwhile, XGL does work fine and stable with fglrx (no 3d of course). Even on a modest radeon 200m, its pretty good. On another note, the image quality of fglrx drivers is pretty good too . Also, I am tempted to say that perhaps X-effects are broken on almost every graphics hardware . ATI - no need to mention. Intel - AIGLX is apparently fluid smooth on a 915/945+ say, but I get pretty nagging artifacts when I play video. (Or I might need some work arounds I guess). Smoothest and perfect on Nvidia cards, but people seem to have the turbocache blacking issues after long time. Atleast I must say 'it works' in case of Nvidia.
PS : After seeing the gtkperf benchmark (never heard of it before , I installed it and was happy to see it giving 160 seconds on the geforce 7400 go in my notebook . Btw - were the tests performed in that same small default window or full screen ?
