Crytek has issued a statement on the forum. "We do understand that a few players are having technical issues with the demo," it read. "We are working to resolve this as quickly as possible, we apologize if it is affecting your experience. We appreciate your patience and support."
The developer ran a beta test for the game, but it apparently didn't catch these bugs or hasn't been able to fully stamp them out yet. Now that it's officially called a demo, fans are holding it up to a higher standard.
as much as im burned out on call of duty, blops ran fine on my pc. never had the stuttering or bugs people encountered.
