jaunty good, except for low video performance...

[surian]

Hi folks
first i wish to thanks the ubuntu studio team for this new release, the
system is always great, thanks!
My new jaunty Desktop is running fine, i can run jack with low latency (5.8)
ans stable using a m-audio audiophile 2496.

The only problem i noticed, so far, is that the video is running far more
low than the Hardy Heron (8.04) I was using till yesterday.
Like, for example, when running an Ardour session, I open the mixer window
and the level bars are lagging/freezin..
The windows in general are opening low. (maybe the whole system is runnin
lower...)

Does someone could help to detect where's the problem?

My video card is a nvidia 8600GT, and i have 1 Gb Ram. The visual effects on
"appearance" are disabled.

Maybe could it be the nvidia driver? I'm using the version 180 that seems to
be the recommended one in the restricted drivers area.
Maybe version 173 (the other option) could work better?

maybe is my memory lock (70%) too high?

I really apreciate your help.

um abraço,    ---> PT(br)
