and what upscaler and settings are you using?
with out a source i woudl say the image is full of compression artifacts that are either amplified with enhanced image details or are there in the first place.
I'm using heater settings from Asmodian thread: Madvr settings explained.
I typed it wrong. The 1080p23 image is 4:2:2. The lowest I could find.

I know those are not the same frames but you can see green blocks on the black background, right? Those are only present in the 2160p23 output.

Could this be related to something I was reading about dithering twice? I don't know how said something that you should not use 10bits on MadVR because you will be dithering twice or something?

Also, when outputing at 1080p23 the only thing I see is chroma beeing upscaled but I'm getting 18ms of rendering time?
This doesn't seem right with a 1080Ti. No dropped frames though.
