I've noticed things feeling pretty sluggish since updating to Maverick (I ran the same kernel and driver on the latest Lucid and it was fine apart from the known vdpau issue). Thought I'd run gtkperf today to find out.

That's about 100seconds slower than it was a couple of years ago (when it was bad), a good 150seconds slower than it should be.
I'm not pointing fingers at this point. I'm just trying to find out where the issue is. X? Some other Ubuntu component (nothing to do with nvidea)? Is this problem known?
