Brigade path tracer comparison

The following screenshots are taken from the Brigade real-time path tracer demo, available at http://igad.nhtv.nl/~bikker/
Rendered with CPU only at resolution 832x512
Images with 100 and 800 spp were taken without frame averaging (only 1 iteration)
Images with 2, 8, 16, 32 spp taken with frame averaging (averaging samples of several frames)

2 spp


8 spp


16 spp


32 spp


100 spp


800 spp



To top it off, one big image comparing 800, 8, 16 and 32 spp. It amazes me that the quality of just 8 samples is already great and with some filtering it could rival the quality of the 800 spp image:
