I max Crysis 2 in DX11 and also with the high res pack, and I get about 40fps on average. It never drops below 30 and often goes about 50. I heard that the human eye can't read more than 30 or so frames per second, anyway. I think the thing that make it look laggy isn't necessarily the 35fps, but the fast drops repeatedly. I have ran detailed benchmarks and have found that a game can drop 20fps and back up again in a fraction of a second. That instability causes lag. I have also ran games in fraps, where I would lock the fps at a low value (30 or so), and it was smooth and lag free. PC games often have the tendency to bounce all over the place with the frame rate, and that instability - especially when it bounces back and forth in a fraction of a second - gives the appearance of heavy lag.
For me, anything under 30 is unplayable. Anything over 40 is desirable. And anything in between is ''meh''.
You have about the equivalent of two 6870s in xfire, so I would think you would be getting 60 fps. Is 3D a hit on performance?

What you "can" see is FAR FAR FAR more than 30 FPS, but our minds do not work that way, the detect change, not FPS. Read this: http://www.100fps.com/how_many_frames_can_humans_see.htm
30 FPS is generally what it takes to appear smooth, but there is noticeable difference in 30 and 60 FPS when you turn rapidly.
The problem for me has more to do with motion sickness or what is called simulator sickness. What causes it is unknown, but the Air Force found that over half the population will experience at least some form of simulator sickness when running flight simulators.
Some people get motion sickness, others get eye strain, and others get headaches. I get motion sickness (nausea).
Back before I experience higher FPS, I used to power through it and have to get used to games and take frequent breaks. With FPS over 40 it is better. With FPS over 60 it's better yet. 3D vision may be worse at lower FPS than normal because it is alternating images between your eyes, which means lower FPS means each eye has to wait longer in blackness (this might be wrong. It might just alternate with your refresh rate, but I still experience motion sickness at lower FPS in 3D vision).
