Flickering shadows Problem Unreal 5.3

Hey guys

So I’ve noticed some odd flickering of shadows on far away meshes. I’ve tried numerous suggested fixes, such as changing the Anti Aliasing to TAA, but that makes it even worse so I set that to TSR which makes the flickering significantly less.

I’ve also tried setting the ‘Final Gather Quality’ of the post processing volume to 8 or 16, and this just does nothing.

Has anyone else encountered the same issue and perhaps have a solution to this? I’ve attached a video showcasing the problem. The flickering happens on some meshes of the castle:

I’d be very grateful for any help in this regard

Thank you for your time
Kind regards
