      Opera is using 100% CPU when trying to watch youtube videos at 4K. But when I watch same video at chrome no issue happened, CPU usage is 25 % - 50% . At 1080P Opera uses 80-90% CPU but it boosts up when switches to 4K. Please look at the issue with care.

      Note that , all my Extensions were Disabled in both opera and chrome during the test.

      Thank you.

        @tareqtareq Same codec is being used on both cases?

        Video decoding/processing has always demanded a lot of the CPU, specially when it can't be hardware accelerated.

            @tareqtareq Right click on the video > Statistics for Nerds.

            It will show the codec being used among other info.

                Hey, any solutions regarding this issue? I was testing Edge lately and it uses even less CPU than Opera and Chrome.

                Would love to continue using Opera for Youtube. But it's heating my PC too much...

                  @marjang hey there, please go to Settings > Enable "Hardware acceleration when available". See if it solves your problem with opera. And please disable other extensions and functionality from Settings which is not useful for you.
                  Thanks.

                    @tareqtareq Thanks, did that solve the issue for you?

                    It doesn't do any difference for me. Hardware acc is enabled. I tried disabling ad blocker, no difference.

                    Opera uses ~90% CPU, while Edge (same Youtube video) uses ~20% CPU.

                      I found out that only Opera on my Windows 8.1 gives me described high CPU problems.

                      On other PC with Windows 10, Opera runs Youtube normally with low CPU use.

                      Anyone else with Windows 8.1 having high CPU issue in Opera?

                        After more testing i found very interesting thing: high CPU drastically drops (to normal level) when i mute Youtube video or mute opera tab with Youtube video playing!

                        Wow, any idea what is causing this??
