No, i know about nanovision, i use it 90% of the time lately, but when i am not i just envy the people who can see the cloaked enemies with their bare eyes. I can also see them, but once they run past me, i cant see them anymore, end up shooting randomly and getting killed by the cloaked person.
Any tips? My eyes actually arent very good. I have eyefloaters, and they dont move too much. In Crysis 2 there is just too much visual information for me to process, it also adds up to the problem.
EDIT: Sometimes i cant see them at all. They are right infront of me, but i just cant see them.
