The best way for SLI is split rendering half the screen and the other for the other half..

Split work better no matter what .. NVIDIA profile now do not have this option but i tried all and it's still better for high textured sim

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.
