I’m just going to go ahead and say this now, do not expect most windows games to run better on Linux than windows. Typically the case is when you find a well optimized game that is CPU bound, or is natively vulkan. Anything else, expect comparable framerates.
I agree with every point you make except for the desktop environment front end.
While it is nice to install a distro with a given desktop environment OOTB, you can always change it, and even have multiple ones installed at the same time. This is typically a better approach to testing out desktop environments because you don’t have to reinstall every time.
Holy fucking shit you are extremely misguided. Are you not aware that the Linux nvidia drivers are proprietary? The only reason that the mesa drivers are awful is because they barely support the 10 series and they don’t support the new instruction set of the 20’s and above.
If you are running Nvidia on your system and it is above a 10 series, you are running proprietary software. Big whoop, steam is proprietary too, so are the vast majority of the games you play on steam.
Hell, nvidia used to be the ones supplying an open source driver on Linux like 14-15 years ago, AMD didn’t have that, only the proprietary driver. DO NOT OWE ALLEGIENCE TO ANY PUBLICLY TRADED COMPANY, that’s exactly why we don’t have good FOSS drivers for nvidia now.
