From the readme:

> A not too crappy GPU. mpv is not intended to be used with bad GPUs. There are many caveats with drivers or system compositors causing tearing, stutter, etc. On Windows, you might want to make sure the graphics drivers are current, especially OpenGL. In some cases, ancient fallback video output methods can help (such as --vo=xv on Linux), but this use is not recommended or supported. (o)

Whereas VLC has a similar option but it's sort of an afterthought and you have to activate it, from the wiki:

> The VLC media player framework can use your graphic card (a.k.a. GPU) to accelerate decoding of video streams depending on the video codec, graphic card model and operating system.
