Hello there!
As far as i know sometimes some fans made patches that improve 3D (stereo) support in games which have 3D support but have some vusial troubles.

So Crysis/Warhead are that games. There is great 3D in there (unlike Crysis 2 and 3 that have no stereo 3D really, but cheap one frame render emulation) but there are some glitches and visual bugs when graphics set to max. To avoide this troubles you need to switch off shadows, postprocessing and low lighting in game that make the games look much less realistic.

I tryed to google much but find nothing so i decide to ask here. May be someone know is there some patch made by fan of the game that can fix shadows glitches in 3D mode in Crysis/Warhead games?

Thanks!
