GPU is nvidia 9500gt with nvidia (256.35) driver. Kwin uses next settings:
Compositing type: OpenGL
OpenGL mode: texture from pixmap
Texture filter: Trilinear
With enabled direct rendering.

The same situation is with blu-ray videos. When I watching 1080p in mplayer and
compositing is disabled — I've got 10-15% of CPU usage, but if compositing is
enabled — CPU usage increases to 70-80% (60-70% falls on Xorg)...

P.S. Maybe I'm sending too many reports, sorry if that :)
