So far, no. I turned it down to the minimum, and no effect. I don't know if it helps, but I'm using a Firebase gaming mouse, model m6, going by the sticker info. That said, it'd be hard to see if the sensitivity was doing much, because it was spinning so fast that everything looks like flashing images.
I did some more experimenting, and it looks like the view will tend to stabilize if I'm in the hallway at the very start, but the view goes crazy again if I try to leave the area. Also, it might actually be wobbling back and forth really fast? It's kinda hard to tell.
Also, my graphics card driver was updated just a few days ago, but it is a bit of an older card - NVIDIA GeForce GT 1030. I don't know exactly which info will help, but I do know debugging can be a real pain sometimes. Might as well throw in anything that might be useful.
