Please write about NVidia's 2D performance problems

I dont think you loose anything with the stable KDE 3.5. You still can run KDE 4 apps - you don't have to use it as desktop.

I'm not interested in running a couple of KDE4 applications in KDE3.5.x - it sounds a bit ridiculous, I want to migrate to KDE4 altogether. Besides there's a burden of running simultaneously a set of qt3/kde3 and qt4/kde4 libraries.

I do want to hope that NVIDIA will do something about that in the nearest future, although the prospects of this are quite unfortunate taking into consideration their kinda mishap with GTX2XX GPUs and $200 million loss related to faulty notebook parts.

I'm a semi-happy user of NVIDIA 8800GT GPU. While in Windows everything works like a breeze, in Linux everythings crawls to the complete freeze.

KDE 4.x window resizing and other operations look like a slide show for me. My CPU usage jumps to 100% on many web pages in Firefox 3, smooth scrolling is sometimes unbearable (Just open any slashdot.org big enough discussion thread).

A simple rotating Firefox 3 throbber consumes around 40% of 2600MHz Athlon 64 CPU.

There's really nothing to be said. Proprietary NVIDIA drivers do NOT support XRender acceleration on 8XXX and later GPUs - so there's really nothing to talk about. For the first time in my life I'm now thinking of dumping my NVIDIA GPU in favour of ATI solution - since I'm eager to upgrade to KDE 4.1 and I ... can not.

Thats true kano, on opensuse i prefer much more KDE3 than 4, Firefox 3 have work fine, how it does work on other people is different thing..
Even i heard some problem on ubuntu/kubuntu people too, meaning KDE3 or 4 , situation, that 3 works better than 4.

I guess KDE 4 creates some problems and in some cases Firefox 3.

I`m Using opensuse 11 with KDE3.5.9 and 8800gts ( g80 ),
2D and 3D is working with no problem at all, i know this is not a issue but i wanted tell that on compination ( Distro+desktop+drivercard ), what i use, works fine and i think many other users have working system too, why thiss so, not 100% sure.

I stop the test, since I can't seem to face the same problem as you guys. Maybe is the Xorg version I am using, since mine is 1.3.0.

I have no problems

I'm using GeForce 7300 with KDE-3.5.9 and nVidia's proprietary driver.
I did face some initial problems with 2D. But after I made the following changes to my /etc/X11/xorg.conf, most of the problems went away:

Option "UseEvents" "on"
Option "OnDemandVBlankInterrupts" "on"
Option "TripleBuffer" "on"

I've got a 6200 something-er-other in my tower. I bought it because I kept hearing how the drivers "Just Worked (TM)" in Linux. Since I'm not much on 3D, I didn't mind the ~1500 fps in glxgears. And before I started testing KDE4 last fall (and before openSUSE pushed Firefox 3 on me), the 2D stuff was just fine.

But when it comes to KDE4 and/or Firefox 3, my laptop (X1300 graphics) literally runs circles around my tower. There's such a huge performance discrepancy that I went back to KDE3.5.9 exclusively on my tower, and only use Firefox when there's a website that gives both Konqueror and Opera fits.

X Window System Version 1.3.0

Well, to clarify, I'm on Ubuntu Hardy, which uses X.Org X Server 1.4.0.90, and gnome rendering is really slow here:

$ glxinfo|grep renderer
OpenGL renderer string: GeForce 8600M GS/PCI/SSE2
