AMD FidelityFX Stochastic Screen Space Reflections (SSSR)

[JeGX]

Stochastic Screen Space Reflections (SSSR) is a highly optimized hierarchical screen space traversal kernel for reflections. To support glossy reflections the ray directions are randomly jittered and the result ist denoised to provide a temporally and spatially stable image.

Luma Preserving Mapper is a tone mapping and gamut mapping solution for HDR and wide gamut content. LPM tone maps the luma of the RGB pixel instead of the colors itself, but it makes sure that tonemap(luma(RGB)) would be very similar to luma(tonemap(RGB)), that is, it preserves the luma of the pixel.

I tested EVGA GeForce GTX 980 Ti SC+ with 441.87 driver on SSSR and SPD samples running W10 x64 v1909 build18363.836 and i7-4790K@4.7GHz and I get no any problems! Probably any GeForce 900 (minimum?) series still work. I'll send here my screenshots soon...
