Description:
After installing the new nvidia driver and restarting, desktop performance is pretty bad. Switching workspaces takes ~0.5 second, where it used to take no measurable time at all.

Problem with:
Nvidia 195.36.08-1

The previous version of the driver was fine.
This task depends upon

EDIT:
X takes 100% CPU as well, when switching workspaces or scrolling in chromium or vim.

switching workspaces in what? gnome, kde?

Switching workspaces in Xmonad makes X use 100% CPU, and is slow as hell. Scrolling up/down in vim (in urxvt) is also slow, and lets X take 100% CPU.

We cannot do much here, report it upstream.

At least for me 195.36.08, with custom kernel 2.6.32.9 works much faster than 190.53 under KDE 4.4. (7300GT)

Anyway nothing to do here. Please report in nvidia bugtracker/forums.

My desktop was unusable, so I downgraded back to 190.53. Strange no-one can confirm.

I can confirm this, on the exact same HW as the OP.
It seems to happen due to more aggresive powersaving defaults.

Setting performance mode in nvidia-settings or fiddling with coolbits can somewhat work around it.
