Real-time path tracing: Sponza teapot (3)

Always love your videos. The slowness compared to other scenes is due the indirect lightning and the scene-complexity right?

@Cyostasys Thanks. Indeed, it is mainly due to the intricate geometry: many rays are trapped and don't find a lightsource (in this case the sky) before being terminated by Russian roulette or max path depth. Scene complexity is less of a problem: it can render a 300k triangle scene very fast on my gpu
