I reset to factory settings and the "only" option I disabled was "preferred vaapi method" and that was enough to cause it to behave like that...I'm not sure what else todo

there's no need to disable 'prefer VAAPI renderer' anymore, not that that is causing the issue

Hi, thank you for helping. here is the on screen log I took just a while ago while playing Tron (.mkv) ripped from blu ray using makemkv I believe
as you can see the severe frame drops and high cpu usage. It does this sporadically off and on every 3-5 mins or so.

I've run in this before, MakeMKV has some bugs, and I'd bet that's the issue here. Run the file through mkvmerge without changing anything and see if the file it produces plays correctly

also toggle on/off VC1 Vaapi doesn't change any thing

from your screenshot, it's an h.264-encoded video, not VC-1, so toggling that setting would have no effect.

Hey Matt I ran it though different converter and it still behave the same. Tried 3 other movies, same result. So far either disable all hard ware acceleration completely or turn vaapi preferred method on solve the problem..pretty odd. Surprisingly that no one else seems to have experienced this issue.
