Landscape draw distance hides but doesn't cull?

Hey, so I’ve been running a ton of tests to see how to get more FPS on my open world game I’m making. From my testing in Unreal Engine 5, first you get a major FPS drop from adding a landscape, and the bigger the landscape the larger the drop in FPS. Then once you add a light, the FPS drop is proportional to the size of the landscape.

Because of this I’m trying to find a way to cull the landscape beyond certain distances in my world. I found out I can visually cull the landscape with the draw distance feature, but from my testing it appears to still be rending the invisible landscape. Even if I turn the entire landscape invisible using landscape draw distance, the frame rate is unaffected. On the other hand, if I actually delete the landscape then the frame rate goes through the roof.

Is there any way to actually cull far away landscape components to where the engine won’t actually render it? As far as I can tell draw distance makes the engine still process and render it, but then not show it to the player.
