@HiAnonym Brave vs Firefox is not a good comparison. You would have to look at Chrome, Vivaldi, Edge, or some other Chromium browser.
A lot of people have been reporting issues using Nvidia. It seems not to be playing nicely at all times, especially with Brave. Some have fixed issues by renaming as chrome.exe or so when it comes to Brave.
However, bulk of things have been getting fixed from people resetting 3d settings or looking through Nvidia in general. You can check out a variety of links I’ve provided in regards to this at Issues with latest release- youutbe and text - #4 by Saoiray
