Sonic Generations is really great. Tons of depth. But with 3D Vision, you're instructed to turn off Stereo 3D in-game and just let 3D Vision handle stereoscopic rendering. If you had TriDef, you could try the same thing.
Trine 1/2 are the only games with in-game 3D controls that I can truly remember having good 3D. I really wish developers wouldn't even screw with it.
EDIT: Just looked and this is a game where Helix mod went and fixed the shadow shaders. So I had that installed too. Wonder if that's why Sega locked things down with in-game 3D. Cause they had shadow issues. Specifically: the shadow would split into two as you increased depth.
You're clearly set on it, so I'm not one to talk you out of it. But I will say this: the size most definitely won't help if you're sitting close to it. You're basically halving the resolution and if you're sitting close to the screen, the interlacing is going to be pretty noticeable.
Yeah, with Sonic Generations I did just that, I disabled the in game 3D and let Tridef handle the 3D, and OMG it looks fucking amazing, I had A LOT of crosstalk before now there's no trace of it, I'm really glad I found this thread.
I tried RE5 a a couple of days ago and I'm really stuned of how good it looks and plays, with Dead Space 2 I had some distortion at the end of the pointing laser making it a little hard to aim, but in RE5 I can headshot all day, next to zero crosstalk and excellent perfomance, grat game to show your 3D IMO.
