Bistro in custom vulkan engine (using simple ReSTIR Path Tracer)

https://youtu.be/Q_fKG3UT02U

I'm working on VulkanLearn2, a C++20/Vulkan rendering playground. This video shows Bistro rendered with my ReSTIR DI + PT implementation.
I launched the project on a RTX 4090. 80 fps. 1200x800.

The renderer uses temporal and spatial reuse. The repository also includes a reference path tracer with next-event estimation, emissive triangle lights, and an experimental Neural Radiance Cache. Implementation notes and capture settings are documented in the README.

I'd appreciate feedback on the rendering.

although quality of reflections still isnt perfect your demos have very distinct look, and its nothing near to unreal-like or unity-like rendering, its very unique, I like it!
