With DRI fps is pretty much constant around 8.0

With this option fps ranges from 7.5 to 12 depending on object view angle.

These are values in fullscreen and no delay. Both cause 100% system
load but the DRI one causes system load and the software one causes
user load.

These are fullscreen values. The difference might be larger in the
small demo in the xscreensaver-demo application. With software
rendering the animation in demo seems smoother and 70% user load is
generated. With DRI it causes a little load in system time.

Thanks
