-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi *,
I have experienced that for some time now but never got the time to ask about it. I have a machine with two user accounts under Kubuntu 9.10 and the performance difference I am experiencing is measurable. The first user account (set up during installation time) works good. Glxgears is around 4000 FPS, video playback is fine, compositing is fine (especially the desktop cube is fast as hell and really smooth). On the other hand there is a second user account (this one is not in the admin group but basic setup is the same). In that user account I get only around 2700 FPS, compositing works fine (the cube is still that fast) but moving windows around is dead slow and video playback is NOT "tear-free". The rather strange thing is that it doesn't depend on video source frame size or codec or scaled frame size, the playback is just dropping frames especially when there is a lot of movement. Turning off the compositing results in a fast user experience but since it is fast with compositing for the first user I expected it to be the same for the second one. CPU usage is not the problem as the quad-core machine is idling around between 70% and 90% although Xorg is between 30 and 50% and mplayer between 1% and 26% (peeks up to 47%) when watching a movie. System: - - AMD Athlon II X4 620 - - 4GB RAM - - Radeon X1950XTX - - Dell 3007WFP-HC 30" @ 2560x1600 This doesn't make sense for me at all. Can someone shed some light on this? Thanx a lot, Ancoron -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAksgNpIACgkQHwxOsqv2bG0nbgCeJ8HmwMHHvMbl3hvije14BpDo 9uoAn2w0+YA8q1SftGXcCR+nyk9WbtEz =44t+ -----END PGP SIGNATURE----- _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
