I got S-3D to work on v1.08 (albeit with SHADOW QUALITY set to "low") and it was nice, pop-out effect was pretty good even on my $4.99 red/cyan glasses (lol... I'm saving money for the iZ3D)
I got S-3D to work on v1.09 but only for one game session**.
While it worked, I have to say: Crysis is beautiful
in 3D. For the time that it worked on v1.09, I was able to run Crysis on High details with the DX9 cheap-tweak on (r_usepom = 1, q_renderer = 3, e_water_ocean_fft = 1, r_sunshafts = 1)
Believe me, when I say Crysis is beautiful in 3D, I really mean it. You really feel like you're IN THE GAME. You're in the game's WORLD. While it worked, I found myself reaching at the monitor for the lush plants that would literally bursting out of my monitor. I even tried to grab a North Korean with my left hand when he got so close because he was nearly popping out of my screen! (it sounds stupid to you right now, but believe me, when you're playing Crysis on 3D in full detail for the first time, you're going to do it too
Performance was incredible too. Granted, I'm on the GTX 260, the second highest card on the NVIDIA market right now, but still, the lowest FPS I was seeing on Stereo 3D was 28.9 FPS according to EVGA Precision.
And the highest FPS in Stereo 3D for me was 55 FPS. I don't think I'm going to be complaining too much about performance.
Again, that was all on v1.09, when you could set Shadow Quality to HIGH. On v1.08, by setting Shadow Quality to LOW, I was getting a minimum FPS of 40.
The one regret I have is that I was unable to play it on the iZ3D monitor. I've heard that on the iZ3D, you're looking at Crysis in full-color and with better pop-out/depth perception.
** iZ3D technical support is currently going out to help me solve my problem. It seems no one else here (except for user iamcanadian) is having the same problem. No games will run on v1.09 for us anymore.
