I have a netbook with AMD zacate system. The thing is doing great job (1080p 60 fps smoothly) in Microsoft Edge, but in Linux with Firefox, movies are choppy (even simple 720p). The issue is that Firefox has blacklisted some graphical drivers.
So maybe 2 things to investigate :
- did you have checked if this issue happen in Firefox, especially Linux distro ?
- about VLC, did you have installed drivers and enabled hardware acceleration in “codec” section ?
Hope it will help
PS : If you have any solution about my choppy videos in Linux, please feel free to tell me.
