Serious cursor movement issue

[Scrape71]

So whenever I move my cursor around in dcs whether it be in the menu or in Sim whether it's controlling the view or not it tanks my fps, like bad, makes it unplayable. I'm normally at around 150-165fps but once I start moving my cursor around the fps drops as low as 30. Ive tried so many different things, fresh install, mt exe only, changed every setting multiple times over I'm at a loss. I'm about to put this <profanity> down and just fly bms from now on I'm really that frustrated. Any help would really be appreciated.

You may be hitting the known problem that effects a few users around the mouse polling rate, your symptoms match. In your mouse software reduce the polling rate to 150 to 250 and see if that helps. If so then increase further till you have problems, needs to be under 1000.

Can you also attach your DCS log file. Just want to rule out any other possibilities, and may also help with the overall analysis to see why this happens to some users.
