Finally got this, looks lovely @ 1920 @ mid settings, looks good enough & I notice the hardcore mode doesn't make it look significantly different so I'll leave it at that for now!
One thing that bugs me is the radial suit menu, in Crysis you clicked, selected & away you went but sometimes I can select stealth, the button doesn't highlight, then by accident I keep seeming to use the binoculars (B is assigned for that, I don't need it on a menu too!)
It seems like it has most issues if you're in cover, as though it wants you to choose that 'peek over cover' or whatever it's called option rather than going into stealth/etc
Still, it's lovely looking, gameplay is 'ok', I'm looving the weapon sounds, very satisfying although a little too much blood splatter when you hit someone.
