I am running Vista Ultimate with a mobile Quadro FX2500M card. An application requiring OpenGL quad buffer stereo support fails, although I enabled stereo in the driver settings (for vertical interlace).
I read in the Siggraph 2006 OpenGL BOF presentations  that Vista does not support stereo, at least in the first version.
Errr, OK. Is Vista Ultimate still this first version? But then the stereo option should not be shown in the driver settings. Can somebody report of a working quad buffer stereo application with Vista?
