In any case, that doesn't have anything to do with the observation made by the forum user. * Thorsten -- How ServiceNow helps IT people transform IT departments: 1.

It's well known that the noveau driver doesn't reach the performance of the proprietary driver ..still? My only Nvidea experience is a coupla weeks now in August on XTX Geforge GTS 260 card on the nouveau driver, while waiting for a new PSU for my 4890. FG frame rates was 15-20ish and I was able to bog it down once I started piling up on eye candy. The big surprise was how the 4890 was decent, but not much faster. (and I have a laptop - pretty hard to change the cards...). ...and pretty easy to swap out nvidea for nouveau in your /etc/X11/xorg.conf once you have the driver installed, you may have to reboot to get kms going right, though. In any case, that doesn't have anything to do with the observation made by the forum user. ..easy now, I haven't tried the nvidea driver yet, I got an XTX Geforge GTS 260 card along with my 4890 radeon card, the 4890 was too tough on my PSU, so I tried the GTS 260 on the nouveau driver and the darn thing just worked, not much slower than the 4890 on the radeon driver, the _only_ thing I did to get it working, was swap out radeon for nouveau and reboot. Easy. ;o) ..the interesting part in this thread here, is I see precisely the same psycedelic rendering errors with the 4890 on the radeon driver, as I see with GTS 260 on the nouveau driver, hence my suggestion you nvidea guys take a nouveau look if you don't have a radeon card handy.
