You need to provide a sample file, so we can reproduce the issue. It looks like mpv/ffmpeg uses 100% of video decode engine on your gpu and that causes frame drops, but we need more information to diagnose why this happens.
EDIT: See also https://github.com/mpv-player/mpv/discussions/13991 for other VP9 performance issues in ffmpeg. EDIT2: There is also unexpected low performance on Apple Silicon https://trac.ffmpeg.org/ticket/10963

you can use this youtube
mpv "https://www.youtube.com/watch?v=bnofYmfKLeo" --no-config --ytdl-format="315+251" --hwdec=d3d11va
Additional: As I have mentioned
Although I have BlackDesert in minimized(which do not consume too much resources), it's abnormal that firefox does better than mpv.
I tested it without BlackDesert. The video can play without dropping frames. However, AFAIK, minimized BlackDesert may occupy vram, but will lower the CPU and GPU usage significantly.
And, I heard that Firefox alse use FFmpeg as video decoder, so I think it won't be FFmpeg problem
Firefox doesn't use ffmpeg as a hardware acceleration method, but uses d3d11 or media foundation in its own way.

Thanks for correcting me, I will check if it's FFmpeg's problem
After invesgating about video decoder in FFmpeg, I found it seems like my GPU doesn't have enough vram to decoding high resolution video when running game int the background.
I confirmed that via taskmgr, in that situation, when I open a high quality video, it increase the vram usage, and starting using shared memory (although gpu's vram is not full).

Reproduction Steps
MPV Software testing 1:
mpv <file> --no-config
MPV Software testing 2:mpv <file> --no-config --profile=fast
MPV Hardware testing 1:
mpv <file> --no-config --hwdec=d3d11va
MPV Hardware testing 2:mpv <file> --no-config --hwdec=d3d11va --profile=fast
Firefox Hardware testing: drag and drop into new tab
Expected Behavior
MPV Software testing 1: maybe slow MPV Software testing 2: maybe slow
MPV Hardware testing 1: fast MPV Hardware testing 2: fast
Firefox Hardware testing: fast
** slow means visable shuttering
Actual Behavior
MPV Software testing 1: slow MPV Software testing 2: fast
MPV Hardware testing 1: slow MPV Hardware testing 2: slow
Firefox Hardware testing: fast
** slow means visable shuttering
