My problem is that I can not see the option in Crysis 2 to switch the resolution to 1920x1080. It only shows as far up as 1280x720. Is there anyway to get around this? Other games I have on my system run at 1080p just fine.

My system specs:
AMD Phenom II x6 1055t (OC 3.4GHz)
4GB DDR3 RAM
Sapphire HD6950 2GB DiRT 3 Edition
750w PSU
CM Storm Scout

Problem solved. There was an issue with the ATI control centre.
