1746496 - VP9 GPU Utilization difference between Firefox and other browsers on AMD GFX9

Status: RESOLVED WORKSFORME

(Core :: Audio/Video: Playback, defect, P3)

Description

[Cyril]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:95.0) Gecko/20100101 Firefox/95.0

Steps to reproduce:

Open a VP9 encoded video on youtube, with a computer with VP9 hardware decoding (my computer is an Inspiron with Radeon Graphics.
For example this video : https://www.youtube.com/watch?v=1Irg5rndzcM

Actual results:

GPU consumption is almost twice on Firefox than Edge.
For example, in 1080p60 fullscreen, GPU consumption is 25% with Firefox, 13% with the same video on Edge.
I checked, the video is encoded in VP9 on the two browsers.
I disabled all extensions, but the results were the same.

Expected results:

GPU consumption identical or similar between the two browsers.

Can you attach the graphics section of about:support as well as a screenshot from GPU pane of Task Manager for Firefox and one for Edge?
