We investigate GPU path tracing performance in the context of real-time rendering for games. We propose a reformulation of Russian roulette, as well as an efficient implementation of the path regeneration algorithm by Novak et al. [Novak et al. 2010]. We show that a combination of these algorithms provides high performance for a variety of scenes. We integrate our scheme into the Brigade system, an experimental path tracer for real-time games, and use it to render the virtual world of a student game at interactive frame rates.
