I am the biggest Stereoscopic 3D (S3D) nerd, I pretty much only play the game in S3D with nVidia 3D Vision. I have an AMD card also and for the life of me I could not get it working with AMD HD3D, I think I have an incompatible monitor. FFXIV is hands down one of the best games for S3D nothing renders incorrectly. I play on an Acer HN274H with SLI GTX480. I have tried all kinds of settings to get the best S3D experience.
Just to clear a few misconceptions. From the begining SE planned for S3D, at E3 they showed the game running in 3D Vision Surround and they made sure everything rendered correctly, this was back in beta. When the game launched it didn't "natively" support S3D which I only guess was a miss-communication with Nvidia because there was a 3D Vision profile for the benchmark and not the game. Later there was an Nvidia profile update to turn on S3D around December after the game was launched I couldn't find the driver number. Later nVidia added support for windowed 3D for Final Fantasy in beta 270.51.
SLI still is not natively supported and I had to do some hacks to kind of get it somewhat working, I only recently got a second GTX 480. I just found out that SLI and 3D vision windowed mode does not play well for FFXIV and I am sure that it will eventually get fixed.
Now to get any kind of good framerate in S3D you need to turn off AO. With AO enabled my single GTX 480 I was getting 15-20 FPS in S3D which I would play with when I was just soloing and doing side quests. With AO disabled I was getting around 40 FPS in S3D which is how I play when I am in a party. I am sure frame rates are better with a GTX 580 maybe someone else has numbers for that. You will want to go into the nVidia control panel and enable keyboard short cuts to play with convergence. Which is under Setup Stereoscopic 3D>> Set Keyboard Shortcuts. With that you can play with the convergence settings and do some neat things.
With 2.0 coming up I hope they don't break S3D with the new graphics engine. I also am excited that they said they were going to add DX11 features after 2.0 launches, again I hope they don't break S3D. When WoW added DX11 they broke S3D with their awesome water shader.
See look I am a S3D nerd I just found this emoticon with 3D glasses.![]()
