I kind of improved the situation by lowering the reflections resolution and removing any shadow from foliage. I’m using the foliage components to spawn hidden imposter shadow casters that use really static (no offset) materials, so no shadowmap regeneration. It seems to have improved the situation, even if sometimes, UE5 decides to bloat in the VRAM. Some days ago, it even told me I exceeded the budget in an empty blank map lol.
