I've been searching around and I've found no other accounts of this particular glitch, this is just one of many places it seems to happen.
So far it happens to me inside caves and on a few hills in the level Ascension. Any Ideas what might be causing it?
well, you are missing textures on some places there (and if your pc can run crysis, that shouldnt be happeneing) maybe you have to reinstal it, but first, see if there is a driver update for your grafic's card.
And Crysis runs on most computers fine at 800x600, as long as they're no more than 2 or 3 years old. It's not nearly as tough on computers as everyone seems to make out, on low res and med-low detail it doesn't take thtat much power.
