Hmmm?  I would have thought your first order of business was to adapt to playing iso's as you requested?  Anyway, I see you are outputting at 60Hz for a 24fps video.  I match refresh rates to avoid the 3:2 pulldown you are experiencing that introduces judder and frankly is unwatchable imo.  Hopefully your display is at least 120Hz capable so you have a perfectly divisible frame rate.  Your frame repeats are excessive yet your stats show there are none.  Perhaps you reset them by pressing Ctrl + R before taking the snapshot which you should never do when sharing.  You are downscaling 2160p to 1080p.  I presume your display must not be native 2160p else you have wrong settings or do this for some other reason on purpose.  I see nothing suggesting you are actually using NGU, instead Lanczos4.  Also nothing to suggest you are HDR decoding anything let alone which method.  Add 2 blank folders to your madVR install folder named 'ShowHdrMode' and 'ShowRenderSteps' to reveal more stats to help you see where your resources are going.
