Okay gotcha, appreciate your breaking down the science. always interesting to learn more about that. Definitely gives me more context into all of it. I have an RTX 3090 Ti.
I tried switching between detailed tracing and global tracing and it gives me back a couple more frames, but definitely not enough. But the issue still seems to be the same. I also tried converting everything to nanite (with the exception of incompatible or non-essential meshes) and it makes no difference. Also nanite static meshes materials get jumbled when adjusting engine scalability in 5.3 lol. But whatever I just run the reloadshader command.
