Wow, that's real nice.. considering that S3D requires each frame to be rendered twice for left and right stereoscopic images. An older GTX 295 does the job nicely as well. What's amazing is that it's playable with an 8800GTX in stereo3D @ Very High settings.

Looks like it's wonderfully optimized for Stereo 3D since comparing it to the non-Stereo 3D only shows about 20-30% reduction in frame rates, or so. Wow.

I guess that's the ideal optimization, since it does not exactly mean twice the physically calculated frames (from frame one to frame two, progression-wise), just that each frame is stereoscopically split into two stereo images, that's all.
