Does YouTube.com consume more CPU / GPU on PaleMoon 33.2.0 on Mac?

Unread post by marigold » 2024-06-23, 15:20

I am using PaleMoon 33.2.0 on macOS Catalina 10.15.7 and noticed that whenever I watch any video on Youtube, my mac really heats up (usually above 90 degrees C and sometimes even touching 98 degrees C). Activity manager shows PaleMoon using a lot of CPU (120-135%) and GPU (10-40%) when the video is playing. Note that these are not HD videos - I mostly watch youtube videos only at 480p (which I set manually) and often at 1.25x to 1.5x playback speed.

I have observed this on a new profile, without any addons running too. The same videos on youtube, when played on Tor Browser, use a lot less CPU / GPU (and the CPU temperature is usually around 80 to 80 degrees with it)

Can somebody confirm if it is the same on Linux and Windows too?

I have not noticed the usage being higher on Mac than other platforms, but there are hardware acceleration patches that can reduce the usage on some video codecs on Mac that have not been applied. They are on my TODO list, but I have not been able to work on that list in any significant way since January.

@dbsoft: Thanks for looking into this. I think PM Mac does need some tweaking. I've roughly observed a general increase of 5-10 degrees C on the CPU maybe from the last 4 to 5 stable releases of PM. (Since I have an Intel Mac, and sometimes do video encoding on it, I constantly monitor the CPU temperature).

Perhaps PM can also benefit from an about:cpu flag like Chromium? Even the basics, like this example Chromium output for about:gpu, should be enough to begin with -
Graphics Feature Status

Canvas: Hardware accelerated
Compositing: Hardware accelerated
Metal: Disabled
Multiple Raster Threads: Enabled
Out-of-process Rasterization: Hardware accelerated
OpenGL: Enabled
Rasterization: Hardware accelerated
Skia Renderer: Enabled

When you install HTML5 media tuner addon (or disable VP9/webm support manually), your mac becomes cooler?
