What happens when the bug occurs? While moving or while adjusting the camera direction, shadows and dark lines on textures will suddenly darken and just as suddenly stop when not moving or looking around. For example running into a building causes the segments where walls are made of different materials to have the space where those materials connect become much darker. Shadows under foliage and on rocks will do the same, as well as the lines on the plants themselves. It almost looks like the game has suddenly become cell shaded, or someone turned up the VividPixel setting found on some Asus monitors. Also, even though I do not have the adaptive settings on, the resolution will randomly turn down and look very noticeably worse. This combined with the darkening issues makes it hard to pick out targets while moving or aiming.
What should be happening instead? The visual experience should remain the same regardless of if im standing still or moving.
Steps: How can we find the bug ourselves? not sure since friends have not run into the issue either

all of my settings are default except for:

brightness 65

minimal sprint shake

ragdolls low

one other thing I thought of was that the nvidia drivers recently updated, I changed physx to cpu since it was crashing borderlands 2
