Tips? Nanovision has been broken since release so that is not a viable option(shame on you Crytek).

Buddy I have had a hard time spotting cloakers since release!

Squint.

For my computer, the nanovision doesn't render completely(only heat signatures register and everything else is black and i cant see if i'm inside a building or out in grass on airport)

Also, if you have an IPS or any recent LCD/LED monitor(Even a 1920x1080) you can set the color ratios to favor the clear blue or red spectrum in order to see "cloak" better in-game. If you do this, however, other games and movies you watch on your monitor will look weird.
