The playback problems are VLC, not the blu-ray drive or the ripping. Try a different video player. As noted, it might be your GPU and/or drivers are outdated relative to playing HD h264 compressed video files.
MPV is the player behind Emby, that's something to try

A mac-native player to check out is IINA. I like it as replacement for QuickTime. I haven't used it for blu-ray rips, but it will likely work fine.
