Firefox use 100% of my cpu and drops frames when playing 8k video (gpu acceleration setting is turned on). Chrome instead have no frame drops and does not use 100% of the cpu.

I tried to google it and use some solution, but no effect in my case.

hardware: cpu: ryzen 5600x gpu: rtx 4070 ram: 32 gb monitor: LC27 JG50QQIXCI (qhd 16:9 144hz)


PS: 1st picture firefox, 2nd chrome.

Visit about:support in the address bar and check the status of the AV1 codec in the "Codec Support Information" section.

Thank you for leading me to the answer. I just need to install av1 codec support from ms store.
