If you’re frustrated by Crysis 2’s almost non-existent selection of graphics options, check out this handy tool. It’ll create a custom .config file that can replace your Crysis 2 one, letting you customise motion blur, anti aliasing, and everything else you’d expect to be able to tweak. Bigdownload has the patch notes, which look like this:

Server Browser shows incorrect pings – Fixed
Some matches never initiate – Fixed
Faster text chat – As speedy as can be
Console re-enabled – Console has been re-activated
Cheat detection – Now in place to ensure all users are on a level playing field
Fix USB headset issues – Current issues have been addressed and fixed
Fix hologram icon staying on screen after being used – Fixed
Remove Auto Aim – This has now been completely removed due to overwhelming community feedback
