System Details

OS: [MacOS Sonoma 14.2.1]
Thorium Version [116.0.5845.169]

Problem The new M3 series of chips have native AV1 hardware decoding support. When playing a 4k AV1 encoded YouTube video, Safari uses around 20% of a single CPU core, however when playing in Thorium, the "Thorium Helper (Renderer)" uses 247% CPU usage.

Please definitely compare not only to Safari but also to Chrome

Please try again with M120 whether the issue still exists.

Same here. No problem on brave, firefox, safari, arc, and my ungoogled chromium build. The AV1 videos on youtube are stuttering like hell.

The only way i could go around it is going into youtube settings and set AV1 only for SD videos. Then 4K videos doesn't stutter.
