Re: Background Pixelation
It's faster than my fathers new 7000€ Dell 18 core on both CPU and GPU rendering.
It's faster than my Ryzen system (8 core / 16 threads but 3.6 - 4.0 GHz) Eventually your 128GB memory (I have only 32GB) are the key for fast renderings...

Re: Background Pixelation
Cec, I can reproduce the pixelation on my system even with your fixed file. If I delete all the floors, the problem has gone. If I recreate the floors, the problem reappears.

Re: Background Pixelation
Cec, this is your file, just opened and directly rendered:
...as you said, no problem.
But zoomed in only a little bit:
... the problem reappears.
The biggest floor is a little bit displaced, so I tested if this can be the problem. But neither push it to the right position, nor delete the floor and rebuild it helps. If you create a second level and then increase the original level by 1mm, you can see strange "rays" on the floors in the 3d view:
I suspect this has something to do with the problem, but I still can not figure out what exactly caused it.

Re: Background Pixelation
I would suggest to create a large white zone around you building, and cut / paste everything else on top of that.
Do you mean create a large white image .png and use this as the background, then copy and paste everything on to that?
Simpler than that: create a rectangle room that surrounds all your design as in the attached file.

Re: Background Pixelation
I'm pretty sure that these "noisy rays" come from how the ground is cut around your home with large triangles that goes from the house border to the far away border of the scene. I noticed that kind of noisy effect in other situations with SunFlow at very high points of view, and it's a reason why I limited the eyes elevation to 100m. Introducing a rectangle room will produce a much simpler cut out in the ground around that rectangle, with smaller triangles around the house which will remain in that rectangle.
