Cinematic Editor Light Artifacts


Hello. New here. Making a VR ARCHVIZ. Having weird real time light rendering. Cinematic Scalability maxed out. Lighting quality: production. CPU 30%, GPU 20%, 40FPS.
This is without Steam VR turned on.

Lighting usually looks great but certain spots, the shadows will be clear and move 2 feet away and its a blurry dots appearing and disappearing. Also have sun blooming through 0.2 Meter thick walls [Sun Bloom only stopped after making the wall 5 METERS THICK]

Nanite on, Static Lighting Off, Reflection and Global Illumination are Lumen, Reflection Res. 128.

I would love to sit here and test every single setting, but basically everytime I change one, I have to restart the entire editor. So any help would be appreciated. I have no idea how to adjust these thousands of rendering settings
