Split frame doesn't share the load evenly, there's no perfect method, you can easily have one half having a huge HDR/shading workload and the other half showing the floor.

On topic: It looks clear in luthier statements that the engine need resource optimizing (should improve memory use), and more fine threading, because the same thread that renders, needs to load finer textures when you'r close to ground, hence horrible stutter you all see.
