Description a_tevelev 2009-12-12 02:47:02 UTC 
If compositing is enabled, switching windows takes 5 to 10 s, while kwin process takes 100% CPU. After a few minutes compositing gets automatically disabled with the notice that it was too slow.

The video card is Quadro NVS 140M/PCI/SSE2. 

The hardware is clearly not an issue - it used to run compiz with all its effects lightning fast. 

Settings:

So... Try with KDE 4.3.5 (stable) or 4.4.0 (~arch) and latest experimental nvidia-drivers? I'm not sure what do you expect from here with this information, pretty hard to support binary-only drivers setup.

No response for two months, old kde version.
