I wouldn't call it excellent, just the opposite, I'm seeing 40+ fps (yes thats, FORTY frames per second) LESS in Linux compared to Win XP in ETQW @ 1600x1200 on a 8800GS... I'd call that pathetic not excellent. Next card will be ATI, fed up of this nonsense, hey nvidia get a grip, open source your driver and let some experts fix it please.

Ok let me try it out. But I do agree with your post. Linux is a more efficient os and you should get more FPS than on windows. I also agree that nvidia should open source their drivers and let experts fix it.

Yup, with my 7800GTX I was getting much better performance in Linux than in XP, but since I switched to a 8800GS the performance is worse in 3D (2D is fine), specifically in ETQW and especially at high resolutions. Basically in the Linux version I have to lower all the details to get any kind of decent frame rate and even then it's not as fast (or smooth) as XP. Got to be a driver issue.

Edit
Ok I did some benchmarks on ETQW, for some reason I couldn't repeat the massive 40 fps difference I saw (but I swear it happened, honest ) but still, the Linux drivers are still slower. Using my own timeNetDemo @ 1600x1200, Ansio & AA off, Low details (gets worse on Normal & High):

Win XP x86_32, driver 169.32, 8800 GS

17365 frames in 172.9 seconds = 100.4 fps
processed 29687 MegaTexture tiles

with Shadows & Smooth Foliage Off

17366 frames in 159.5 seconds = 108.9 fps
processed 30025 MegaTexture tiles

Gentoo Linux x86_64, 2.6.23-r9, 169.09-r1 driver, 8800 GS

17364 frames in 204.9 seconds = 84.7 fps
processed 30709 MegaTexture tiles

with Shadows & Smooth Foliage Off

17366 frames in 182.9 seconds = 94.9 fps
processed 30722 MegaTexture tiles

Looks like a ~15fps difference, storm in a teacup? No because when you watch with AddPerformanceQuery com_showFPS enabled you can see the min/avg/max frame rate is much higher in XP..

Hey, I'm a gamer, every frame per second counts

Serious question: is the focus (within NVidia) for 3D on Linux games, or is it compiz?

The reason I ask is that save slow scrolling in FF3, I have no reason to complain about the 3D performance of this 8600GS* in this HP under compiz/Emerald and while watching movies, moving windows, etc.

no, different graphic architecture. X is slow. Face it. Windows graphic system is optimized for speed. As long as they don't do something stupid (Vista) they are always faster.

That said - the performance with KDE4.1alpha/beta/rc1 is really, really horrible. Yes, I was wrong in the past. It is bad.

I don't think they have any focus at all. But since they use large parts of the Win driver for *nix, you'd expect that everything that's needed for Win does work well. Traditionally that is OpenGL, which is most important for both games and compiz (I think).

In nvidia marketing language, it is the 'User Experience' they care about.

Some games are faster for me on Linux than on xp (but some are slower, maybe nvidia don't provide acceleration for some 3D functions in Linux driver as they don't provide for 2D?). I don't know, but when playing in fullscreen X maybe don't affects performance and maybe X affects only 2D performance (but not too much if ever, because Ati drivers do very well in KDE4)?

Always kde4 here.
with the nv driver scrolling in firefox is a bit better, while resizing/reducing windows still is horrible. Moreover, with this driver i see some ugly horizontal lines on panels and on the splash screen.

I'm going to put aside my kde4 session for a bit, at least until they release a fix or a new driver. Thanks, nVidia.

I tested this one with the nouveau driver and get ~5fps, just the same as with the nvidia driver (8-series GPU).

At least in that respect the nouveau guys have already caught up with nvidia.

Suit yourself, but in the past I have always gotten better performance on Linux than on winbloze. We just don't have good enough of a driver to compete. Once we get that, we're all set.

Does anyone know when we can expect this to get fixed?
I paid $100 for a better card to realize that compiz works worse on the more expensive card.
I used to like NVidia.

They said they're "working on it" but no one knows if it's going to be next week or next year.
