Strangely, films that were 2.39:1 or similar plays on NGU high perfectly. Is this normal? Does it really take more processing power to work with 1.78:1 images?

If so, is there a way to set a rule in MadVR to select NGU medium with 16:9 movies and NGU high for everything else? Right now, I use a rule between 1080p and 2160p like you explain in the tutorial you referenced. I would like a rule within this to select 2160p and then determine whether it will be NGU high or low.

I hope that makes sense. Thanks Warner.

Yes, it's normal. More pixels to process require more computing power.

There's definitely a way to achieve what you seek. Read this https://forum.doom9.org/showpost.php?p=1...ostcount=3 and you'll find all relevant information on how to write rules in madVR to select profiles based (in your case) on resolution and aspect ratio.
