Hi Tom, I changed the driver to 96.36 and it seems to work better. However, still the computer sometimes slow down and freezes for a while when moving a molecule (pdb: 1ii6) with the mouse. It seems to happen in particular when rotating the molecule with the mouse after zooming in (by clicking the right mouse button and moving the mouse). Thanks Hernando Thomas Goddard wrote:
Hi Hernando,
I tested our Quadro 900 XGL graphics with Chimera 1.2422 with a map and PDB model (1a2p pdb and xray density ~170^3) and saw not problems in about 5 minutes of use. Tried both Linux (Fedora core 7) and Windows XP. The Windows driver version was Forceware 91.36 (7/12/2006). The Linux driver version was 96.31. The machine has a single Xeon processort, 2.8 GHz and video bios version 4.25.00.22.03. It is dual display.
I noticed in Windows there are quite a few Nvidia "performance and quality settings" (right click on desktop, Properties, Settings, Advanced, Quadro 900XGL tab). Ours were set to use global driver settings and the defaults (restore button grayed out).
