It’s not a low end system but it isn’t high end either.
You should be aware that Lumen at “Epic” scalability is expected to run at ~8ms on next-gen consoles including the PS5 (roughly equivalent to a 5700XT, supposedly) at 1080p. They’re targeting “High” scalability for 60 FPS projects.
In terms of optimizing, it’s not easy… There are hundreds of cvars for Lumen that you can tweak but none of them are documented. I asked about better scalability options in the Lumen thread and was assured they were focused on providing better options in the future. For now probably the best thing you could do is render at a lower screen percentage.
I would also note that you should not be profiling in editor. Use a standalone process or packaged project.
