Hi Chris, I haven't tried the last few years but some time ago it was possible to patch/hack nvidia drivers so that consumer nvidia cards could produce quad buffered stereo. That was officially only possible on the expensive professional cards.
The fact that you say that the current consumer cards and professional cards are still very similar (not surprisingly), maybe it would be possible to use a similar trick... Like this: http://stereo.jpn.org/eng/stphmkr/help/opengl.htm As I said, I don't have a clue what the current status is. regards Raymond On 3/10/2010 6:53 PM, Christian Kehl wrote: > THAT is the question of the day ! > > I asked that question in the last month once a month the AMD/ATI guys (in a > bit more formal and kind manner).
