With all due respect to Linus, the opinion of a developer is of no consequence. I understand his frustration, but we're talking about end users here. Nvidia is still out there, Linux users will still want to use Nvidia cards (which have better value for money when it comes to power/upscaling/frame gen/etc.), and Linux on an Nvidia card is not horrible. I know that's the party line; I've been running Linux for 30+ years, and I see the lies that get told. Nvidia gaming on Linux has been very good for a long time, and 99% of the distros out there make it braindead simple to install and keep the driver up to date. The two greatest weaknesses have been : 1) Wayland (that's basically fixed now, I ran Wayland for a year on Nvidia and it's quite good, especially on KDE), and 2) DX12 performance. The latter is the main obstacle to great Linux gaming support, and I have no doubt it's being worked on. It's not impossible to run DX12 with good framerates on Nvidia in Linux, but it certainly has some bad performance regressions.
I'm not saying you have to like Nvidia, or use Nvidia hardware, but these "Nvidia support on Linux SUCKS!" propaganda that gets fed to newbies is harmful. It might cause them to go out and buy hardware that they really don't need to, or worse yet, just not bother with Linux. It's disingenuous.
Valve is opening SteamOS to traditional gaming PCs. Starting with SteamOS 3.8, users will be able to build their own Steam Machine from the PC components of their choice. This should be especially interesting for those who are not convinced by the price or performance of Valve's official Steam Machine.
