Description of problem:
3d acceleration (glxgears, compiz, composition, etc.) is very slow on my Lenovo Thinkpad X60s
Version-Release number of selected component (if applicable):
Enable desktop effects. Scrolling in applications like firefox becomes very slow, exposé becomes slow, windows visibly fade in and out (i.e. slower than intended).
Regardless of desktop effects active or not, glxgears shows around 330 FPS, about half of what the same hardware produces with Fedora 8.

Lenovo Thinkpad X60s Hardware information
I have the same issue, at least with Compiz and everything being very slow. I have the Intel 945Gx chipset. It is very pronounced when I move a window or resize a window.
Also, if it helps, I am running on a Dell Latitude D520 laptop. This was not an issue on F9.
Please let me know if there are any details or specific information I can add.
Ditto Dell Inspiron 6400 with Intel GMA 945. Painfully slow...
This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle.
Changing version to '10'.
