I have tried many different things to solve this including Apparently some NVidia Chipsets don't actually clamp the Negative LOD Bias to zero, so setting it that way in the Inspector or Control Panel does nothing.
Through research, I have found a possible reason is that this is Temporal Aliasing being caused by Bethesda's notoriously bad Negative LOD Bias. This effect has been described in the past as a 'Shimmer' or 'Flicker' when moving, but I don't know what to call it.
Unfortunately, my game has a lot of graphical artifacts or pixels showing up on distant objects whenever I move, and I have yet to find a way to make them go away. I have recently installed the wrapper ENB in order to add environmental shadows to my game and to allow me more freedom in changing its graphics.
