Maybe this could be better and faster than current solution? https://www.disneyresearch.com/publicat ... denoising/

Could it be... the next step for light caching? 8-)
Already seen it before but decide to look closely at it today and it is really really mind blowing. Also notice that the more probes you have better will be the quality and rendering are always under 1scs. so we can match Brute Path tracing in just minute easily or with Beefy CpU or Opencl version on GPU in just few sec.

Looks like a good solution for games, maybe if 2.8-eevee would have this it could be pretty nice.
I'm not sure if this is a solution for caching that would work in tandem with pathtracing. Looks more like a completely different approach for GI than something you could mix with pt. it was impressive how it worked with glossy reflections though

Seeing how well recently DLCS works I think if that could be used as basis for ILCS(which I guess is how it's gonna be) it will be best solution. But I wonder if it also can help with rough glossy reflections similar to vray's lightcache.

Normally upcoming ILCS is more robuste than Vray light cache (it is suposed to be unbiased) so i expect less limitation.

"A Simple and Robust Mutation Strategy for the Metropolis
Light Transport Algorithm"

looks like it could be a simple way to increase the performance with little overhead.

Image
Multiple importance sampling seems to work with reconstruction. Three sampling strategies fused by MIS: central pixel BRDF sampling, neighbor-stealing BRDF sampling, light sampling. Here in glorious 15fps on my GeForce 940M :P It's all specular btw, even the diffuse-looking walls

im pretty sure this idea the kelemen mlt paper. a variation of this is already implemented at the heart of luxcore and is available as the metropolis sampler

obviously ,i don't know much about this but If I knew how, I'd be willing to spend free time training the denoiser for luxcore.
