My whole level is 1 mesh and the light map resolution is 512
As far as i know lightmaps dont affect lumen as it it dynamic lighting

Ah, you are right about the lightmaps. I’m afraid I don’t have much experience with Lumen yet. You could try disabling Virtual Shadow Maps in Project Settings->Rendering->Shadows->Shadow Map Method. Adjusting the Lumen quality settings in a post process volume might help as well.
