When viewing things through the PIP sniper scope at a very high distance it is occluded by fog (lower draw distance)
Enabling 2D scope does not have this problem

I hope it's possible to add more options for this!
Pip scope view distance could be an option.
I also think the PIP should have quality options or a resoultion slider.
I would also suggest an option which will SWTICH the scope PIP with the normal world render (the unzoomed area around the scope).
This means PIP(lower quality/secondary render) would be the outer area, while the scope itself should be the main render.
This would provide higher quality vision of the most important thing(INSIDE THE SCOPE),
while allowing lower quality settings for PIP view(OUTSIDE OF SCOPE),
blur effects to mitigate the lower quality pip render even further to allow for more performance friendly options.
