Black box appearing in certain places??

I'm pretty sure it's something to do with my graphics settings but I can't for my life figure out what it could be

It's always when I turn the camera to this angle and cross the FC house's arch, and in a couple of other places as well.. The screen also gets noticeably darker, then fades back to the right tint when I move away. I wasn't able to find if there were any solutions already posted yet unless I'm just blind as a bat.

I don't know if some of these other settings were added recently into the game or if that's nvidia having updated and doing that itself but here are my settings

Sorry if this is the wrong place or format or whatever, I'm new to this.
