I did a comparison like this before for our own project but I just did another one using your tree.
The Static Mesh version you sent me didn’t have LODs so I have disabled LODs for the Blueprint version too to have correct comparison results.
There is ~12 FPS being lost for 1 tree. Sum up the rest of the meshes, that’s a lot of performance being wasted.
