Brave hasn’t been around as long. A lot of times you’ll have places cater to the mainstream brands. For web browsers that would be Chrome, Edge, Firefox, and Safari. This is where we have to sometimes go in and tweak minor things to make sure it all can run just as smoothly.
For example, you have https://www.neowin.net/news/yandex-alleges-amds-windows-drivers-unfairly-favor-google-chrome-microsoft-edge/ which discusses:
AMD drivers would crash over five times less and would eat up on average, 8% less memory when these drivers would detect the “chrome.exe” file.
But seems to be all sorts of issues out there. Another one is https://www.nvidia.com/en-us/geforce/forums/game-ready-drivers/13/529146/possible-cause-of-the-chromium-checkerboard-bug/
Nothing ever seems to be as simple as it once was. And those are of course just trying to go through and figure out solution if it’s something between the browser and graphics. There’s even been times where people discover it’s an extension or something. It’s all one big time consuming headache to figure out whenever someone does have an issue.
