When I have an empty map, I get a very high FPS. During testing, I noticed that the biggest performance hit comes from the trees. I downloaded them from a Quixel project called 'European Trees, with all textures set to 128x128. I’ve enabled Nanite support and set ‘keep triangle percent’ to 0.3, but I’m not sure what else I can do. I’ve also checked the lightmap density, and everything seems fine. Do you know of any good videos or documentation that could help me?
