Visual Bug / Hindrance

I have a issue where on some maps, especially cloudy maps, I can see some weird form of specks / dots that appear on the ground but also on my plane - mostly notice this in ARB. Anyone else seen this or know of a fix?

Graphic Settings - Max Everything
PC Specs :

32GB 3400Hz RAM
Everything on NVME drive

So that said, pretty sure it is not to do with my PC.

What I have tried -

Increase / Decrease visual settings
Every Post FX Setting possible
