[2019] Inconsistent Mouse Sensitivity After Spectre Rising Patch. Anyone else experiencing this? (PC)

After updating to the latest version of Black Ops 4 about a week ago, I noticed my mouse sensitivity wasn't like before. It felt like the sensitivity kept going up and down randomly, at times being normal and a moment after being so low that it felt like dragging the mouse through mud to turn my character around. Went ahead and tested other games as well to see if the issue was in my mouse itself or Windows, but none of them had the same issue. I even tried scanning and repairing the game files through Blizzard App without success.

I noticed that it may have something to do with framerate, like when there's a small dip in the framerate, the sensitivity drops periodically too, making it difficult to track enemies consistently.

Anyone else had the same issue? Keep in mind this never happened before the latest patch and my settings haven't changed in the game nor in Windows.

My system specs (if relevant):

-Intel Core i5-4690K

-Nvidia GeForce GTX 1060 (3GB)

-16GB DDR3 RAM

I also play at 1080p144Hz

Thanks in advance!
