The “Auto Intermediate Resolution” option in the two pass processing section doesn’t work as expected when Nyx is the second pass.
For example, if I select the final output to be 3840x2160 (2x the original resolution), then select Gaia as the first pass, then Nyx as the second pass, I would expect this:
Gaia 2x → Nyx 1x
But instead it does this:
Gaia 1x → Nyx 1x → Lanczos 2x
This seems to be because the “Auto Intermediate Resolution” option is acting as if Nyx is a fully fledged upscaler with 2x and 4x variants when it isn’t.
Example of settings I used:
