Same stats as below with a microfacet material scene: 3:57

Final Gathering: 10,000,000 photons, 8 bounces, 20 max photons per lookup, 16-128 spp. 8 bounces. 8-16 samples per light. 23:47

Same settings as only indirect lighting, but with direct also using my photon map. 1:22

Photon Mapping for Indirect Lighting. 1000000 photons, with 500 max depth for the trace. 8-16 samples per pixel. 3 max bounces. 1.5 radius, with 1000 max photons per lookup. 1:21 render time
