Ambient occlusion is fuzzy/pixelated/flickering

I'm aware this happens in other games, but if there is some way to improve it, I would appreciate it.

This issue has always existed for me since I started playing years ago, but I am hoping there is something that can be done as I appreciate its effect in buildings but looks not well otherwise.

Made two clips of it in different whether scenarios:
DayZ ambient occlusion
Ambient occlusion - no rain

Adjust the level and it gets especially bad at medium.

I tried each level with different levels of post processing, hardware antialiasing, and at 1080P and 1440P.

NVIDIA App settings Default.
