I cant figure out why mp4 videos are choppy, stutter, lag, or dont play at all

The steps ive taken to fix are....

tried to convert/change bps, fps, resolution
change cache value
turn off hardware acceleration
compatibility mode
disable/change decoding
change video output module
re-encode file
copy file to new container
change container format
reinstall vlc
reinstall operating system

It seems your hardware decoder is struggling to keep the pace. Try disabling hardware decoding and/or changing video output
