I can confirm this on Kubuntu 8.04 64-bit. I have 2x nVidia 8600GT cards, using the closed drivers (installed via envy).
I'm not clear on how the themes work, but I'm guessing that KDE wouldn't be using the GNOME human-murrine theme, so I suspect that is not the issue for me anyway.
The above linked GUIMark benchmark gave me results of 20+fps on WindowsXP and ~0.25fps on Kubuntu.
This is a quad core system with 4gb ram and 3 disks in RAID5, so I can't see it being related to overall system performance. I have unfortunately never been able to get KDE to run without the closed 'nvidia' driver, so I can't give the benchmark results on the 'nv' driver.
