Hardware Acceleration Issues when playing multiple videos

That means it’s not an issue with Brave but is an issue with your graphics card or graphics settings. I want you to search this site using the search terms @saoiray nvidia and you’ll see a lot of topics where people have complained about issues. You’ll likely want to sort it by Latest Post.

You’ll also see links shared and suggestions. Most importantly, you’ll see how people had their issues resolved based on doing things like resetting their graphics card, updating graphics, or changing settings like MFAA or background frame rate.

If you don’t know how to search the site, you can read Search Before Posting and it teaches how. Or I guess can be nice enough to link to https://community.brave.com/search?q=%40saoiray%20nvidia%20order%3Alatest which should auto search and sort for you.
