Try disabling the Microsoft Infrared Transciver through the device manager and running Crysis3 to see if the tilde works then.
That fixed for both Crysis games!thanks for the help!Of course I'll have to reuninstall it each time I reboot which only takes a few seconds,thats easier than going to the registry or disabling my auto driver update.
What are you able to do now that you can use the console?
