The critical problem is that my diplay must be configured at 1900x1200.
I can easily reduce resolution to 1280x1024 (or lower), but from what I
understand, pixel depth will remain the same. Isn't it true that a
medium pixel depth is required for doublebuffered stereo?
Is there any way to implement stereo (top/bottom or otherwise) with graphics
initialized to 1900x1200?
At this point, I'm willing to use any resolution and any video field
rate...
