Hi everybody,
watching http://toowam.france3.fr/test/casse-noisette/ with adobe flash player
is very slow with nouveau. On my nv17 on a athlon XP1800+, 46.1091 % is eaten
by nouveau [1] (the guilty seems NVDownloadFromScreen [3]).
With nv, eat only 0.0254%. [2]
This mean using nouveau make impossible to watch this flash animation.
