Lol. Steroscopic 3D has been in ATi Cards since the 5xxx
No. They announced their "HD3D Initiative" , making it sound like the 5xxx cards had something special that the previous generation cards did not. I waited and waited, but nothing ever materialized. Only very very recently, some monitors have come out supporting it, however their stereoscopic solution has ABSOLUTELY NO driver support - they rely on third parties! Tri-Def and iz3d are the ones supporting HD3D, not AMD!
NVidia's solution is all done in-house inside their drivers, so compatibility patches can be very quickly made, and game compatibility is MUCH higher than with IZ3D or Tri-Def's solution.
