4k activating subtitles causing high CPU and GPU usage

"Throttle transcodes" does not slow down ffmpeg but it will pause it once it gets ### seconds ahead of the current playback position (configurable). Same with delete segments. Deletes transcode segments ### seconds after you've passed them.

Jellyfin Media Player does not truly support HDR, btw. Due to limitations in some of the libraries used to build it, HDR is not possible. But a re-write is currently in the works.

In the mean time, Jellyfin MPV Shim does support HDR rendering, but requires modification to do so. Read this thread.

As for the CPU/GPU usage, I'm assuming it is transcoding. Not sure why it would since JMP should direct play nearly everything. Unless you've configured subtitles to always be burned in.
