Seems like gamsradar has no idea that it's up to the TV whether polarized or shutterglasses are used and "ghosting" is a TV issue and has nothing to do with the game.
Furthermore they didn't detect that on TVs that use polarized ones the screen resolution is halved (per eye) ..
apart from that Crysis 2 itself doesn't take much of a performance hit (only few %) in 3D mode, because it uses 2D plus Z instead of double rendering the scene to achive the 3D effect and it's good to hear that the effect doesn't seem to suffer from that approach
