When I play a video from odysee.com on LibreWolf it uses 2-3x the cpu that Brave does to play the same video. It also turns on the fans in my laptop which signals overburden. My laptop has plenty of power so I"m wondering what the problem is. Have I missed a setting or is this just how LibreWolf works?

Well, but how bout hardware acceleration for everyone else? Windows (which I’m on rn) doesn’t seem to have it

@Kidplayer_666 On Firefox/LibreWolf look at page: about:support -> Graphics -> Compositing. If it says "WebRender (Software)" it is not using HW accel. If it is using HW accel it will just say "WebRender".
on Chromium/Chrome/Vivaldi etc. look at page: chrome://gpu/. You want to see "Hardware accelerated" and not "Software only. Hardware acceleration disabled".

Yes, I'm on Linux and LibreWolf compositing says: WebRender (Software), my Firefox however says WebRender without the "(Software)" and Brave says "Hardware accelerated." Firefox and Brave consume similar normal amounts of cpu. LibreWolf does not.

So if my Firefox has acceleration, then shouldn't LibreWolf also? Do I have to add it or enable it somewhere? Thanx

@opt9 Looks like you found the issue. Did changing those settings fix the problem?

Yes, setting these 2 to True fixed the problem. I am curious if there was a security reason for this, or if it was just oversight.

@opt9 I'd bet that they just missed it. Glad it's working for you. 👍

Now I went and checked Firefox and those same 2 settings are also set to False by default, BUT Firefox does not have the same cpu overuse problem when playing video that librewolf had before I changed these 2 settings. I am trying to figure out what's going on so I can make a helpful recommendation.
