This sounds quite sensible. I now also tested the cube-version on my
Intel-laptop. I also get very high load, though only about 80 percent)
and crappy performance. Disabling the gemhead of the snap2tex lets CPU
usage drop to about zero immediatly. 

Maybe it's a problem with the OpenGL libraries or with AGP on my
systems. One is a Debian, the other an Ubuntu box, and I didn't do any
special configuration. 

Maybe some other Debian/Linux users can give some hints here?
IOhannes, you are running Debian as well, btu I guess with NVidia...

Ciao
