Is it me, or is the mouse control...iffy? I'm not sure if there's anything that can be done regarding it, but it's making the game seem far more difficult than it needs to be. Anyone else find a good solution or sensitivity?

After installing (with anti virus OFF so that dll file is left alone) I started the game and have bad lip sync problem and mouse moves very erratically ... took me about a minute to highlight and click on OPTIONS ... set options on LOW with the Lowest resolution I could and restarted the game only to have the same problems. I don't think my computer is good enough to run the game with the Enhanced HD improvements ... Perhaps your computer is Better so it (almost) works ...or do you also have the lip sync problem in the first cut scene as well ...

ONE NOTE however regarding the antivirus situation ... IF you don't set an EXCEPTION for that .dll file ... next time you run a scan OR defrag ... It will be quarantined again ... Found that out when I ran a defrag to try to get more power to run the game.

It seems like the mouse movements have a delay. It's not my computer speed as I have good frame rate. Is this happening to everybody (intentionally designed like this by the developers?) or is just sporadic?

Ok, so for my "lagging mouse" issue I found out what was causing the problem. Having V-sync on is what caused the lag. When I turned V-sync off, it returned to normal and quite responsive.

Does anyone have other ideas? I have the same issue, but I have V-sync off. Right now, the game is unplayable. It's basically the same no matter what resolution I try as well.

I had the same problem and solved it by switching anti analyzing off and going to a lower resolution 1240:720

still had to lower the mouse sensitivity a lot because every time I shot/punched it kept jumping up or down

The ONLY thing I had to do is make sure AA was at least 2 from the highest setting. I had hi res and everything. Tjhat's all (and some in-game adjustment).

Hello, I have the same problem. I can play with higher resolutions without any lag but the mouse becomes uncontrolable and the slightest move will cause a 360° change of direction/view. I tried all the solutions suggested on this thread and elsewhere but the only way that really works is to change the res to 800x600. Game is finally playable but... ugly.
