After some experimenting with image codecs, I think I'm managing to define a new codec fit for anime content. Some interesting artifacts due to how it chooses the block types based on the perceptual metric. So far it seems I'm beating JPEG in compression!

Procedural sky with Nishita model, DoF, RTGI, AgX, RT shadows, all 11ms total on 1660ti with bottleneck being RT Shadows.
AgX for colours, bokeh depth of field and some grain give everything a nice filmic look.
Depth of Field with noise from RT reflections looks like walls are covered in sprinkles
Finished initial implementation of radiance caching, surprised that it even produces decent and kinda-stable results (even tho a bit leaky).
Temporally-unstable and rather low-res Rem. Reconstruction errors?
Tried to render Bistro in my engine, looks nice but this French guy was on some drugs
Importance sampling really helps, glossy reflections converge into a good-looking result almost immediately.
Heard people like irradiance volumes
Ray-traced shadows spatiotemporal denoising!
Working nicely, but too many samples. And it's still noisy, there should be a way to calculate direct and indirect lighting separately and do GBuffer pass instead of doing primary rays to fetch material data.
Alright, double-bounce path tracing, each bounce samples a Lambertian random direction around the normal (simple importance sampling I guess).
Entirely not physically correct, but looks kinda nice
1spp primary + 1spp for shadows, for sure amount of shadow rays, can be reduced with NdotL importance sampling (there's no need for any shadow rays from a completely shadowed area), but not sure what to do with noise, need some sort of spatiotemporal filtering?
Vulkan + Raytracing, finally. It does even work on my GTX1660Ti. Random shadow sampling, even with many samples, doesn't give smooth results.
