@Cato501 - I've explored with several browsers and this seems to be an issue across most Chromium browsers. Brave and Opera GX seems to be the lowest of the two impacted with this bug, but it can still have an issue under high loads. I know this from personal experience.

In the past few days, I've been playing Dead by Daylight and Final Fantasy XIV on my PC with Twitch in the background. I've thought their updates were the cause of my PC crashing (memory issues, exceptional issues, etc.) and randomly shutting off (once the memory issue was resolved), so I started to monitor the CPU and GPU processes for a few nights. From what I can conclude, it seems to be an issue with the media player and loading onto the website. This is what I've tried doing to resolve the issue and failed:

• Removed Hardware Acceleration.
  Mitigates somewhat, but either screws up other elements of websites or offsets more resources onto the CPU. This depends on the browser. So, this isn't the solution.

• Control Panel settings and messed with GPU elements.
  The only thing that helped me were disabling 3D elements and limiting them in NVidia Control Panel, but this went out the window last week. Messing around with settings in the browser didn't seem to make difference.

• Changed and disabled third-party extensions / ad-blockers.
  Since the issue appeared to be another player issue, I wanted to give a shot of trying third-party extensions and ad-blockers. Firefox didn't seem to work and Opera doesn't have many add-ons to mitigate this problem. Can't mitigate the issue here.

• Lowered the video quality to 160p.
  It does mitigates, but still has a leakage. This was surely for the sake of seeing what's the core problem and it seems to be what's attached to the media. This alone seems to be causing a majority of the media player's bloat.

• Rolled back NVidia's Graphics.
  I rolled it back for a few specific versions to see if it removes the problem and thought it resolved. Nope. It caused my PC to shut down while I was gaming and had Twitch on a second monitor. No blue screen, but the culprit was overheated CPU.

Yeah. This is a lot of troubleshooting I've done over the past few days, but this issue was giving me a lot of hair-pulling and made me stop doing almost everything to resolve it. Unfortunately, there's only one real solution there to resolve the resource hog issue with Twitch, Youtube, and other websites constantly abusing for "higher quality" content.

The temporary solution, until a more permanent solution comes around, is this:

• Utilize FrankerFaceZ add-on and disable auto-play on all Twitch videos.

• Pop out the Twitch chat and keep it in a different monitor.
  You can substitute this with Chatterino chat client.

• Install the latest version of Streamlink and VLC.

• Use the Command-line Guide in your CMD.exe window to start watching!

This helped me cut about 20~40% CPU resource bulkload from the Chromium browsers.

@gyrotakashi -

If you guys don't want to utilize Streamlink, I do have a few other options to try:

• If you open about://flags/ in Opera GX, these are the options [1] [2] I toggled in the experimental panel that helped reduced some of the stress load on the CPU.
  You may not have to toggle all of these options, but these are what helped me.

• Nvidia's Control Panel for the Opera GX Browser (same as Opera.exe) was turned down to the lowest settings possible for CPU and GPU settings. #1 #2
  You can alter a few settings from mine for your personal preference, but this works for me.

• You can increase the memory cache in your computer to compensate for your memory issues, if the issue is related to it. (I did have a memory BSOD related to gaming and twitch running together.)

This is the result of how my browser is running with a Twitch stream running at 1080p60FPS:

Again, I had 50-70% CPU usage prior to this and had leakage issues on Youtube and Twitch. This solution may not work for you guys, but I figure to throw this out to you guys.
