This is due the fact that compiz uses OpenGL to do it's rendering and it's code is also better to interact with the Xserver. > > When you say that the algorithm can be calculated in the GPU, you mean there > is a setting I can change to do that, or is this a feature that needs to be > implemented? The feature must be implemented in gnome-mag. This is not so difficult, since there are lots of good code that do this, these just have to be merged inside gnome-mag. Making this will improve the Xrender performance (the actual implementation) and will also give 3D acceleration support. > > Thank you, > > Aurelian > > > On Thu, Mar 27, 2008 at 6:02 PM, Carlos Diógenes <[EMAIL PROTECTED]> > wrote: > > Hi Aurelian, > > > > Probably in a Core 2 Duo you will have 50% of CPU usage (100% of one > > core).
