Some things i have tired:
1. Update nvidia drivers. I am running the latest version which is compatible.
2. There are no overclocking tools.
3. My i7 is running stock speeds
4. I have repair the installation via origin.
I did come across this bug in the screenshot below. The crysis screen shows dx10 but I am running dx11. Is there some sort of conflict?
Specs:
Intel i7 2600k
