Expected video performance on r700 based cards?

[Dennis J.]

Hi,
I just upgraded from Fedora 10 i386 to Fedora 11 x86_64 (by means of a new 
installation) and have noticed that video performance is now worse than it 
was before under F10 even though general 2D performance seems to have 
increased quite a bit.

What should I expect in terms of video performance on a 4850 card? Before 
playing 720p videos consumed relatively little CPU power but now I need a 
full core to play them.

Regards,
