I use WindowMaker (and tried KDE shortly from another local user) and under KDE it's even more sluggish because of the enabled desktop effects. So it likely includes the 3D/OpenGL performance as well.
Example: CSS3 transitions in FF4b are much smoother on my slow laptop with Intel graphics compared with my powerful workstation having the nVidia card.
What's your Xorg doing? Is it chewing up 100% CPU while you're experiencing the sluggishness? Are you finding that the computer becomes completely unresponsive for 1 or 2 seconds at a time?
This sounds a lot like what I experienced with my system with nVidia... on another system with intel graphics, the problem didn't show up at all and KDE4 works fine using default drivers and kernel.
My solution for the nVidia/11.3 sluggishness problem was to bump up to the 2.6.35 kernel. Someone else has had success with booting with vmalloc=192M. I haven't tried the vmalloc boot parameter, but moving to 2.6.35 made a HUGE difference in my KDE4 performance.
You can get the 2.6.35 kernel from this repository: http://download.opensuse.org/repositories/Kernel:/HEAD/openSUSE_11.3/
C.
This sounds like the problem the kernel developers had before with the 2.6.34-git8 and up. That's why they removed the git versions for 2.6.34, incorporated it in the 2.6.35 RC1 version and corrected the problem there. I have problems with 2.6.34-12 too with or without nvidia drivers in that the system is always unresponsive when switching desktops.. There are more problems with 11.3 so I have gone back to the 11.2 version awaiting the 11.4 version to correct all the quirks.
