A couple of days ago Crytek launched their second Crysis update. The patch is about 360MB in size and it will update your version to 1.2. Apparently, it should improve the game’s performance, and we’d definitely recommend downloading it since a couple of frames extra never hurt anyone.
DX10 performance is also improved and there’s a list of minor bugs that were fixed and you can find it on the official site.
You can download the patch here.
