8800 ultra stereo driver

[Dave]

Thanks for the reply Deltcho. The Z800 is a frame sequential device and my understanding is (is this correct?) that the GEForce cards need to have the external stereo driver to emulate quad buffering. Is it the case (as I think it is) that if we had one of the NVidia quadro cards with hardware quad buffering we could just include the viz.QUAD_BUFFER command to achieve the frame sequential video output. If so does anyone out there have any experience of comparitive performance (speed) of say the Quadro FX1700 (512MB) (around the same price bracket) compared to the GEForce 7600GS (which works in stereo) and the 8800 Ultra (which works but not in stereo).

That is correct, the stereo drivers are simply emulating quad buffering. I don't have any technical performance comparisons, but Quadro cards are usually sufficient for most uses.

Hi - thanks for the help so far - I now have a quadro 1700 with the 162.52 driver that came with it which I think is going to be ok but am having trouble getting the emagin z800 to show a stereo signal. I have exported an executable only version of the routine, including viz.go(viz.FULLSCREEN | viz.QUAD_BUFFER) - this seems to be sending a frame sequential stereo output through the DVI/VGA converter ok - on a standard monitor it shows as alternating images in which features converge as you move towards them. Unfortunately the emagin z800 shows the same - it is not sending alternate images to the left and right eyes but both images to both eyes - the led is constant yellow. Is there some cunning setting in the NVidia 3D settings that I have missed - I have the stereo set to ON, set to single display performance mode but am not sure which Display mode is best - have tried all four with no joy. I have tried the force stereo shuttering on and off but no joy. Not sure what the buffer flipping mode does but it is on auto. Anyone any thoughts or a list of the 3D settings that work with the z800 and a quadro board. Thanks
