I can't answer these questions without more information.

Please use the provided Watchdog tool with option 1 ("report a bug") to start MP in debug mode, then play a few videos for ~30 seconds each to show the stutter. While each video is playing, press [shift] + [1] (ie. !) to show the rendering statistics on screen, then take a screenshot. Finally close MP. You can attach ("upload a file") the screenshots and zip file produced by the Watchdog to your next reply. If you want, feel free to upload one set of log files for the powerful GPU, another for the less powerful GPU, another for the CPU etc.

P.S. If you have more than one GPU active at a time, that in itself can cause stutter... especially if MP is not on the primary display/monitor.

No. It means that the system's default GPU is doing the processing. CPU is only used if (1) DXVA is disabled (ie. "none" is selected) or (2) if DXVA cannot be used (eg. video format not supported).
