Comment 49 for bug 252094

Hi Carl,
The issue I'm seeing with EXA is that window drawing (2d) performance is very slow to the point where it feels like I'm using a very old system with a vesa driver. Minimizing, maximizing, or dragging windows around is laggy. Not unusable slow, but probably a good 10 times slower than with XAA. I don't have the desktop effects enabled (although I believe AIGLX is turned on). I don't know of a good way to benchmark window drawing performance but I would be happy to provide some hard numbers instead of my subjective "goes slow" statement if there's a better way. There was a Video BIOS update for the T61
(http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-67988)
that I installed to see if it helped but it didn't. From
the release notes:

"(Fix) Intel GM965 Video BIOS was updated to v1668 to fix a blue screen error
issue on the Windows Vista."

Just let me know what additional information I can provide.
Thanks,
Dan
