jamiehavok: Ok the targeting problem was down to ati drivers, turns out 11.6 kills it and downgrading to 11.4 suddenly all my targets and health bars come back. also restored my saved games by reinstalling the 2 patches - duh!.
crysis 2 still has crappy crossfire scaling though! i hate pcs sometimes.
That's weird, I thought 11.6b or something else newer than 11.4 fixed it. I'm not an ATI user though. I've seen a few threads floating around with the same issue.
