Lumen, shadow noise, foliage and performance

Hey Ironic, thanks for helping, I did try disabled them (contact shadows and Distance field lighting), but didn’t notice much improvements:

Also i tried tweak the parameters :
Virtual Shadow Maps in Unreal Engine | Unreal Engine 5.5 Documentation | Epic Developer Community

I also disabled the visible in ray tracing but the shadows gone, but i got you.

i’ll test Nvidia Rtx GI to see if will happen the same effect, i’ll post the results here.
