@PcChip Yes thanks. What is your CPU?

Try latest release and see if it persists. https://github.com/Alex313031/Thorium/releases/tag/M105.0.5183.0

@PcChip Hows it coming.

from thorium.

it seems that both Thorium and regular FireFox render youtube videos as "Render/3D", whereas Firefox Nightly renders it as "Video" according to intel_gpu_top. When rendered as "Render/3D", it is not as smooth and stutters and drops frames.

I assume that's related to FireFox Nightly recently enabling VAAPI by default?

from thorium.

@PcChip Thorium has patches to enable VAAPI and VDPAU by default as well as it can. This is strange that it is not working on a new chip on ubuntu.

It uses CPU +50% when decoding video and 0% intel-gpu-top video.

I fixed hardware decoding on my instance by clearing the flags on ~/.config/thorium-flags.conf (copied from chrome)
and also resetting all thorium flags on chrome://flags

from thorium.

so on a fresh thorium install on linux, you had to change flags or a config file to make Thorium use hardware video decoding?
