Same 1080p movies use around 6-10% of cpu in 11.04 and 11.10 shoots up to 50-60% of cpu usage in 12.04 with vdpau and mplayer (all under Unity 3d) . I have tried several nvidia drivers and the results are the same (Nvidia current 295.40, 295.20 and 295.33 32 bits) Videocard is Nvidia G105M This seems to be a Unity rather than a Nvidia bug as cpu usage drops back to around 6 -10% for same movies in Gnome shell.
