With DRI fps is pretty much constant around 8.0 > > BTW, you can force the swrast driver by setting the environment variable > LIBGL_ALWAYS_SOFTWARE=1 even when the DRI is enabled. > 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 Michal -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
