[Chimera-users] Windows 8.1 and nVidia Quadro drivers.. grrr

Hi Kenward,

  Here are screenshot images of the two Nvidia control panel sections with 3d settings that we use on one of our 3d vision nvidia Windows machines.  This uses a very old Quadro FX 3700 graphics card, and possibly an older driver than you are using.  We had a Quadro K4000 on a Windows 7 system six months ago and got stereo displaying on it without trouble.  But we returned it because of graphics driver bugs associated causing very slow selection in Chimera.  We reported that problem to Nvidia and we believe it is fixed in recent drivers.

	Tom

The latest non-beta driver is installed.  It took me a while to find where the nVidia control panel is located after finding that Chimera didn't recognize any stereo-capable hardware (including some references to togl and pixels).
