I note: GUI format 1920x1080, Display 3840x2160 @ 59.940060 - Full Screen, for the purpose of testing can you keep to 1920x1080x60 on the Nvidia (2017?) and don't update library on start, turn off refresh rate and sync and let's see if you still have the issue.

Update:
- many video files (e.g. good-quality remuxes) actually never have problems when playing on Kodi on my NVIDIA SHIELD TV Pro
- however, certain files have terrible stuttering problems but ONLY when played on Kodi on my NVIDIA SHIELD TV Pro. These problematic files do NOT have any stuttering issues when played on my PC using VLC, or even when playing using Kodi installed on my PC.
- when logging was enabled and I was observing stuttering on a problematic movie in real time, I noticed that
CPU-KODI was showing around 350%. With movies that play normally,
CPU-KODI typically shows around 50-75%. So it appears that a CPU bottleneck-type issue may be happening in some situations for some reason.
- when Kodi on my SHIELD is stuttering on a movie it doesn't like, the play/pause button becomes almost completely unresponsive and the video will continue to play for up to 10 seconds before slowly grinding to an eventual halt, after being told to pause.
- when Kodi on my SHIELD is struggling to play a problematic movie and is stuttering, a Kodi overlay frequently appears in the middle of the screen, showing "100%", which seems to indicate that it was about to start buffering. It's like it's
just playing enough frames not to stop playback and officially start buffering, despite the fact the frame rate massively drops to an unacceptable level during playback anyway. I'm surprised it bothers to play stuttering content and doesn't just buffer further ahead, until it has enough frames are in memory for playback to be acceptable.
Summary:
The problem only occurs when CERTAIN files are played on Kodi on my NVIDIA SHIELD TV Pro (i.e. not with all files).
The files that the SHIELD
does struggle with have no problems at all when played using Kodi on a PC. If the files were corrupted, why would Kodi struggle with them on the SHIELD but have no problem at all on a PC?
Does no one have any clue what's going on? My issue is 100% repeatable with multiple files - so this must be fairly widespread. Is this a rare issue? Is this forum just less active than I thought?
Is there a better place to ask for help than here?
