I finally started this game up today, and wow. I can't believe this constant hitching every few seconds. Apparently it has something to do with USB ports and a racing wheel. You need to potentially disable a number of USB ports in device manager to get the hitching to stop? F that.
That's correct. And codemasters doesn't seem to be in a hurry to patch this issue (or many other issues). I really regret buying the deluxe edition.
