Help with weird mouse deadzone…

Hey guys, just loaded up the game after not playing it in several years. I originally played it several times over on my Xbox, but decided to buy it for my PC (showing the devs some love). When I loaded it up I noticed this bizarre deadzone issue with the mouse. Tried a different mouse with no luck. Also tried turning on/off V-sync and other options but nothing seems to get rid of it. Anyone have this issue and found a work around?
