However, there haven’t been any engines capable of offering such a feature in the last couple of years. And even though we’ve got some path tracing engines lately, like the Brigade 2 Engine, we’ve still have a long way until we get games without those annoying noise side-effects. Or not? According to Samual Lapere, OTOY’s graphics developer, Playstation 4 might be able to offer real-time ray tracing in a couple of games."
