Version 188.8.131.52 (Official build) canary (64-bit)
Specs: iGPU: Intel HD 3000, dGPU: ATI 6850m
Issue: Livestream playback is not as smooth and lags behind EdgeHTML by 4 seconds when compared side by side between EdgeChromium and EdgeHTML.
Background: A general issue on Chromium exists concerning accelerated video on switchable graphics devices causing an internal blacklist to be employed for these systems resulting in the blocking of video hardware acceleration for the iGPU and instead utilising software rendering. dGPU is not used at all. This being not optimal itself.
Hence for this test the blacklist resulting in software rendering in EdgeChromium was disabled (#ignore-gpu-denylist was set to Enabled under ://flags) to enable Hardware Accelerated Video decode on the iGPU. All other flags relating to acceleration were unaltered.
The situation revolves around the iGPU not being utilised as well on EdgeChromium compared to EdgeHTML. It is questionable if video decode is really being utilised at all with the blacklist disabled.
A Live Stream was started at the same time and compared side by side.
MSI Afterburner/ Sysinternal Process Explorer were used to see the utilisation of the iGPU (noted as GPU2 on afterburner) between EdgeHTML and EdgeChromium.
EdgeHTML utilises the iGPU at 14%-20%
iGPU 14-20% usage on EdgeHTML
EdgeChromium hovers around 8-9% (blacklist disabled - supposed hardware video acceleration)
iGPU 8-9% usage on EdgeChromium - Blacklist disabled
EdgeChromium hovers around 8-10% (blacklist enabled/software rendering- default setting)
