Please keep in mind: The following details are referring to CryEngine 3 (CE3) in general and can't necessarily be linked with Crysis 2!
At gamescom 2010, Crytek's field applications engineer Sean Tracy showed to PC Games Hardware a live demonstration of CryEngine 3 in stereoscopic 3D. Of course in real-time ("What You See Is What You Play") within the powerful editor Sandbox 3. Instead of rendering each picture twice (=half the framerate!) and projecting it on a dedicated 120Hz LCD monitor, Crytek simply uses the back buffer and the depth information in the graphics card: The rendered frame is practically being cloned and the fractum shift procedure makes two out of it. Thus, on the one hand there is nearly no performance drop and on the other hand stereoscopic 3D might be possible on any display - no matter if it's on PC or consoles. Crytek calls this technology "Screen Space Re-Projection Stereo".

wait, so does this mean we can play Crysis 2 on a monitor thats not 120Hz?
Seeing as they were using stereoscopic 3D, no. Technically, the 3DTVs/monitors/projectors are the only ones that can accept true 120 frames a second over DVI/HDMI/displayport. So shutter glasses make that 60 frames per eye. With anything else, its 60 frames, only 30 per eye, which for 3D will look bad and has a higher chance for headaches and all those other problems people complain 3D gives them. Even if people wanted to do only 60hz 3D, stuff like 3D Vision, the best 3D experience for PC, doesn't support anything but 3D monitors/tvs/projectors.
All this is doing is performance optimization. Instead of literally rendering the game twice, one for each eye at a different angle, which is what every other game does, they've got their "Screen space re-projection stereo" tech. So now we don't see the halving of FPS while in 3D, but still get the superb 3D effect. Other companies need to take advantage of this tech imo.
