Bazzite works wonderfully even for non techy types. On mobile at least, NV drivers are working well but there is a performance penalty. Surprisingly, when the windows drivers are CPU limited, the linux one is actually performs better but, generally, there is a performance penalty on linux. AMD GPUs have parity except for Raytracing, at least from what I've seen, RADV performs below the proprietary driver on Windows.

Bazzite comes with Nvidia support out of the box.

I'm not personally running Bazzite, but before I switched to an AMD card, Nvidia worked just fine for me. Bazzite being more streamlined and gaming-specific, I can only imagine it would do perfectly well running Nvidia.

Practically speaking, we are at a turning point regarding Nvidia on Linux. Things were bad before but they have improved significantly. Newer drivers from Nvidia are partially open-source and they seem good so far.

As long as your GPU isn't too old, it should be fine. Bur you should verify before commiting.

I've had some issues with NV cards, but those were prior to the newer open-source driver architecture which should be available for Turing cards and beyond:

I've actually got a laptop with a 2070 so I'll try that out myself and see if it resolves some of the issues I know I had with the proprietary drivers
