The Outer Worlds looks amazing in HDR. I can’t get a good screenshot but wow. All the neon pops. Also Deus Ex Mankind Divided.
SK can take screenshots in HDR and tonemap them to SDR for Steam games.
Before I release 0.11.1, I will have to make that feature work for non-Steam games too.
The Xbox Game Bar can take HDR screenshots and tonemap them, but SK does a better job (its tonemap is sensitive to luminance, whereas Game Bar is tonemapping color and detail gets lost in gamebar screenshots).
Quick question: if my tv is 800nits max luminance, and I set SK to 800 nits max, should the paper white amount be about half? So 400
You should probably keep paper white in the 150 - 300 range, anything above will likely raise blacks and over-brighten midtones. Though of course, adjust it based on the content.
