It looks like the FOV is overflowing with 3x1 (above ~179°) causing the camera to be flipped upside down.
It should be possible to fix it with 3x1 with Cheat Engine assuming Denuvo doesn't interfere. (If the price and amount of DLC didn't already..)
I can't test this due to not having an ef/s setup and resizing the game's window being too difficult.
For anyone who wants to test it there's a demo that's not listed on the Steam store page here:
https://steamdb.info/app/572460/To download it you can make a desktop shortcut of any Steam game, right click that shortcut, and change the number (appid) to 572460.
So the shortcut should look like:
