I would try to figure out how to replace the lighting in your seen with point lights and lowering the emissive power on the material.
Try turning off lumen.screentraces 0 (default is one, and just look up lumen and screentraces, its the command with the amount of letters, I forget exactly)
Might want to start in this forum.
As for the commands, go pick TAA or TSR in anti-aliasing Method in project settings.
the commands only work with TAA for 1080p at frame rates higher than 45fps. But TSR, TAA, DLSS, XESS, FSR, ETC, LMAO, are all temporal filters that blend away noise from lumen.
Excuse my jokes, I’ve had a good day today. But I’m serious about the temporal filters.
