Re: VDPAU slower than software-only?
I just wanted to note that NVIDIA is aware of the VDPAU/PowerMizer interaction issues on some boards (i.e. the problem where VDPAU is slow unless glxgears is run, thus kicking up the GPU performance level) . We are working on fixing this, and making good progress. A fix should be released in a future 185.xx driver, although it's too early to say exactly which one yet.
