Gotta love the stupid bugs. I expect problems with every game launch... i.e. Black ops with its major lag issues. Although if I remember correctly that was more on the steam side of the launch. WoW Cata, had its stupid bugs at launch and alot of those werent even fixed untill a recent major patch. Then on the other hand you have games like CoDMW, CoDMW2 with a MAJOR errors, to the point where people cant play or they just dont want to because of it. Im talking bout the "iw4mp" error, people said it was a microphone problem. (Turns out on mine it only occured when ever I wanted to play with Ultra settings.) But something that was a known problem from the first CoDMW was knowingly unfixed and released with the CoDMW2 with no intention of ever fixxing the problem. So all I say is give it time and all things will be updated and we can go on our happy go killing ways.

Hope Crytek adresses this issue soon.
