When I play youtube videos, they aren't really smooth. The low-res video playback in window is quite ok, but the same video on full-screen, or higher-res (720p) video (even worse) are not smooth (about 10 - 15 fps) and tearing occurs.
When i connect TV (Full HD) via HDMI cable, results are even worse. Performance is poor (few fps for 720p video) and tearing is also more visible. Cpu is about 90 - 100% in use, both cores (Core2Duo, about 2GHz)
I'm using Ubuntu 12.04 with gnome classic, compiz is disabled. AFAIR It also happend on 11.10 and 11.04. Once I tried fglrx, results were porobably better, but now I'm not interested in using fglrx anymore.
I tried both Flash (newest Adobe plugin installed) and HTML5 youtube versions, results are similar.
Tested in Chromium, newest from Ubuntu repo (I assume it's not browser related, so I didn't check in others).
I know it's probably related to the lack of video acceleration in open source radeon driver, but is there anything I can try to get it working with some better results ? My gf's notebook with on-board Intel graphics is working much much better (smooth playback of same videos, no tearing).
