TL;DR:

Before:

An image showcasing the old de-noiser

After:

An image showcasing the new de-noiser

These images are 2 weeks old and there have been some changes to it, as well as a slider to adjust de-noising. Notice how much more pronounced the ambient occlusion is, and how much better the overall shading is. It's also faster than the older implementation.

On the scene I used for testing this out, the overall rendering time went down from 3 minutes to just over 1 minute in an RTX 3090 Ti with an 8K lightmap.

Bonus: This PR shaves off a massive chunk of the codebase (about 10% apparently.) Expect faster build times and a smaller engine size in 4.2!

Holy shit, 114k lines of code being blown away? That has to be some sort of record for efficiency gain.

I'm interested in comparative gains for lower-specs scenes, like 1k lightmap. Also, was that gain on Vulkan? Have you checked OpenGL 2 and 3, or it won't work with them?
