Comment 69 for bug 760814

I'm also experiencing this issuel. I didn't notice this mentioned before.
KDE (in all it's opengl-accelerated/composited glory) has normal performance.

I'm thinking that may rule-out any calls in the call-stack lower than compiz...

I'm on a 4ghz (overclocked) i5 and an nvidia gtx 460. I'm using the proprietary nvidia-current package.

Last thing: Jockey reports that the drivers are installed but not in use. Probably a fluke with jockey, but worth mentioning...?

Thanks, everyone, for working hard to resolve this!
