Default Re: vdpau slowness with 260.19.06

no it's not the case my machine has 4gb of ram and just after starting x and trying vdpau i didn't load any other app, I've also retried now looking at top and it seems i get about 100mb used during the whole testing with qvdpautest (i had 1,77gb free memory (as not even used for cached or buffers) at the start 1,54gb during the test)
this time actually i had some weird results it seems it has improved

I think I’ll be going to reboot and test if these results are consistent

edit: after the reboot the situation worsened again....
