EdgeHTML/Spartan utilises the iGPU for video playback.
EdgeChromium does not and falls back to software. This causes lag, slower performance, bad video etc.
Chromium has a pretty big problem with the lack of utilisation of GPU acceleration for quite a few mobile devices with switchable graphics . i.e. iGPU (Intel HD 3000/4xxx) + dGPU (ATI/AMD 5xxx /6xxx etc).
Chromium keeps a "blacklist" of a lot of devices and automatically switches GPU acceleration off. "Enabling the override software rendering list" via edge://flags does not make a difference.
Whilst Chromium does indeed see that a switchable graphics solution is being used it however is not able to utilise the dGPU at all and does not stress the iGPU whilst playing videos. via edge://gpu
@VonCrisp - Thanks for the feedback. Could you please attach the output from edge://gpu on the system where you're hitting this issue? If your GPU is blacklisted, then enabling the edge://flags/#ignore-gpu-denylist feature should allow hardware acceleration to be utilized.
I've filed an internal bug to track the other aspect of your feedback (utilizing the dGPU for video decode / processing when the iGPU is blacklisted).
