DK2 Shadow bleed fix?

Hey everyone!

Managed to get my unreal project running in the DK2 at 75fps! But I have a huge problem. I am in a darkly lit room, I then turn the lights on in game and there is an insane amount of shadow bleed. It is as if the shadow moves like a wave as I rotate my head around the room. Please can someone help me fix this issue?

I have played a few dark environment games in VR and never seen this problem before!

Any help would be amazing.

Cheers!
