differences in performance between windows and ubuntu

[feanor3]

Important Information

Provide following Information:

• mpv version 0.32.0
• Linux Distribution and Version Ubuntu 20.04
• Source of the mpv binary apt install mpv
• GPU driver and version maybe this?

• Reproduction steps

  On windows I'm able to run the first shader of "lower-end gpu" of Anime4k without loosing frames on a video, using my laptop with ryzen 2500u and vega 8 graphics. On ubuntu, which I've installed on an external ssd but I run on the same laptop, the framerate with shaders is the half (30 instead of 60fps).

Expected behavior

Why does this happen? Hardware is the same, except that the ssd is connected through usb. Thanks.

try using gpu-api=vulkan to see if the performance increases, also on my experience with a weaker cpu than yours using ACNet instead of anime4k gives better quality and performance. Another thing that might help is to use a newer mpv, look for 0.34.0 do NOT use 0.33.x as its broken with vulkan using vaapi (at least that was my case until yesterday with an intel igpu)

Performance differences in this case is mostly down to drivers. In general on Linux you want to be on up-to-date kernel and mesa versions (also mpv versions).
