I'm in the middle of the bonus campaign and there is now constant stutter, even when in menus, inventory, hacking blocker IC, running, standing still, conversations, whatever. Stutter, stutter, stutter. Often I can't even click on the conversation option I want because of the stutter interrupting me. Game was perfectly fine until today's patch. The instant I applied the patch the stuttering started, and now the game is totally unplayable. Thanks.

edit: very strange, after finishing the mission the stuttering was gone. It came back on the next level, then disappeared again, and hasn't come back since then. Very strange. I've changed nothing on my PC and no hardware is likely to be failing as it is all very high quality, burned in, and recent.

edit2: Nevermind it came back again in the last mission Tai Po, exact same lag/stutter
