I have had similar problems on a macintosh G5 (dual 2.5 GHz, Nvidia GeForce 6800 Ultra DDL graphics card). It sometimes suffers from a progressive slowdown of command execution over 5-10 minutes of use and eventually becomes unusable. Save session, quit, restart program, restore session fixes the problem temporarily. Evan Sadler On 8/20/07 12:11 PM, "Tom Goddard" <goddard@cgl.ucsf.edu> wrote:
Hi Hernando,
I think we have a Quadro 900 XGL in the lab which has not caused the computer freezes you observe. I'll look when I am at the office tomorrow (Tuesday) and check which driver that machine is using. It is possible that the graphics driver problem is only seen on dual processor or dual core systems, because the processors can simultaneously contend for use of the graphics.
I do not see any Quadro 900 XGL problems reported on our graphics driver bug web page:
