Low performance for browser with nvidia gpu

General system Newbie

Brave is laggy and stuttering a lot when put on an external monitor connected to an nvidia GPU. Connecting the HDMI cable (through type c hub) to the AMD iGPU seems fine.

Also, I notice that the prime profile tab in nvidia settings is not there too if it makes any difference.

If anyone has any idea how to solve this or needs any additional information, please do say. Thanks! In the meantime, I will try downloading some native games off steam to see if it’s just an OpenGL thing.

Oh well, installing nvidia-prime then running prime-run as root seems to have solved the issue

It is not supposed to run as root. You may have created problems to your configuration. Check permissions in your home folder.

I thought it was a setting meant to run as root so I just went ahead and sudo it. Just tried running it as a normal user, and it went fine, thanks for the info!
