Crysis 2 Engine error- Glitch

I've fall off the map after changing some parameters in Nvidia Control Panel. I have enabled FXAA and after that all sort of thing started to happen. In-game graphics settings set to Very High, DX 11 Enabled, Tesselation Enabled, Hi-Res Textures ON.

My config: Intel Core i3-380M @ 2,53Ghz
4 GB DDR3
500 GB HDD
nVidia GeForce GT 540M 1GB, Latest drivers installed.

Excuse the bad quality of the video. I was recording this with my Lumia 710 in the worst lighting conditions...
