SS2 Remaster - Painfully slow mouse in MDF mode?

Hi all

Finally a long last after 20 odd years on my backlog,, I'm making my way through the series :) Just finished SS1 Remake and flipping loved it and just started SS2 Remastatered.

Unfortunately, I'm having an issue though that is somewhat ruining my experience. In shoot mode, my mouse is fine. Sensitivity is great and I can happily move the camera with ease. In MFD mode though it grinds to crawl and I have to swipe several times just to get my mouse around the screen. To get from the inventory to the bottom bar is 3-4 full swipes which gets annoying really fast.

The in-game sensitivity only seems to affect shoot mode and not MFD mode. Is this a known issue and is there a fix?

Sorry if this has been covered but struggling to find info on it.

Also, now that I think about it as I'm typing, I finally played Thief earlier in the year too and that did something similar in menus but was not an issue since you're not in menus that often. So maybe an engine issue?
