@ogredale FYI according to your provided info, you are running Vivaldi with your integrated GPU (which is pretty good anyway for browsers), and if you want to run Vivaldi with the discrete card you can use an environmental variable using PRIME, or a utility that switches GPUs on the fly using that, or disable the iGPU in your UEFI alltogether -if possible. "Possible" because some laptops require the iGPU to display the UEFI settings, there's a terminology for that that I don't remember now-. The latter could mean more battery consumption though, if you care about that. You can find more info how to set things up in your distro resources I suppose (forums, wiki, etc), especially "gaming" distros dο (or should) provide more tools out of the box for such hardware configurations afaik.
