Somehow it does matter at some point in the rendering process. So to try out the biggest impact we can:
- use a 4k hdr bt.2020 10bit 23p remux (HDR passthrough is fine)
- use a 4k monitor/tv
- set "12 bit" in nvidia CP
- set "10 bit or above" in madVR
- and use the highest setting you can with madvr chroma scaling (e.g. NGU Sharp @ High)
All these settings are real life examples, not some demo material settings.
@huhn, do you have a 4k display? If you don't have 4k remux files then I think guys posted some samples in the
tonemapping topic.
