I have another suggestion.
I believe you may not have the patches installed for Crysis because in 1.1 I think they added in a tickbox for Vsync. The patches were also released to aid performance so I think you should go and hunt them down and install them.
One thing Ive also read about with Crysis is that enabling Triple Buffering in your graphics driver control panel can help.
Give it a try?
