I can confirm that Flash videos are choppy, no matter Compiz is on or not, but only when they are in full-screen mode in my case.
Well, I have made several reinstalls since last week, and the problem won't disappear: when Compiz is activated, fullscreen videos are really slow in VLC, SMPlayer, etc. Compix effects are really slow in larger windows. However I noticed the following thing: if I set the procesor frequency to max through the Gnome req scaling monitor (1800Mhz) while Compiz is on, videos and effects are a lot faster (except for Flash vids). Don't know if this means anything, but it seems to me that the current driver is not really optimized to use composite with my X1250 card... and that it needs the processor to do the calculating job. Correct me if I'm wrong :o) I have the current values in glxgears: >>> with procesor at 800Mhz cristoba...@chris-karmic:~$ glxgears 1518 frames in 5.0 seconds = 303.546 FPS 1367 frames in 5.0 seconds = 273.295 FPS 1455 frames in 5.0 seconds = 290.883 FPS 1458 frames in 5.0 seconds = 291.383 FPS 1427 frames in 5.0 seconds = 285.288 FPS >>> with procesor at 1.80Ghz cristoba...@chris-karmic:~$ glxgears 2958 frames in 5.0 seconds = 591.518 FPS 2919 frames in 5.0 seconds = 583.795 FPS 2847 frames in 5.0 seconds = 569.261 FPS 2940 frames in 5.0 seconds = 587.825 FPS One more remark: I have activated the xorg-edgers repositories, so all of the values come from tests made with the newest releases. If it helps, I have attached my Xorg.0.log. i have not attached my xorg.conf file because I have not tweaked it. Thanks!
