Another thing to keep in mind is the engine is using a renderer designed to scale well with large scenes. The light overdraw in this test is only around 1.0, so it's too small to see the difference it makes. As scene complexity increases, the lighting requirements don't change...it just processes lighting on the final pixels, regardless of how many polys make up the scene. So this engine can display scenes with real-time lighting that would be impossible in many other engines. The engine renders large outdoor scenes without any problem. We'll have some more demos later to demonstrate this point.
If you graphed Doom 3 and Leadwerks Engines in performance vs. scene complexity, Doom 3 would start off faster, but would decline faster with scene complexity, and in more demanding scenes, Leadwerks Engine would run much faster. This is similar to how the STALKER engine's deferred renderer works.
So Puki, a much larger scene with the same number of lights will run at about the same speeds you are getting now.
