Nvidia here under Linux, been running Nvidia hardware/drivers for about five years now with little in the way of problems. The latest hardware is supported on release, and my performance while gaming is fantastic.

Even Wayland support is maturing under Linux running Nvidia hardware/drivers, to the point whereby it's mostly as usable as Wayland gets now.

At least you have the option of running the latest Nvidia hardware under Linux, it seems dedicated GPU support under MacOS is dwindling by the month.

Yes this is true as lots of Nvidia users have told me otherwise, when I used a rtx 2060 on Linux for about 6 months before I switched to a amd rx 6700 and it's been the best experience I have ever had in gaming on a PC in general honestly. Nvidia "works" in terms of installing the driver, playing games do "work" but the big issue is vulkan shader loader on steam and then third party games that run on lutris, bottles that require specific environment variables for the game to not stutter or to switch to dxvk async as a instant fix for loading shaders but async is being kicked out because it's a hack and includes a lot of patches the devs don't like.

You can turn off the vulkan loader as Nvidia has a way of loading shaders rather quickly, but it does it in the most stupid way possible that example in apex I had to wait 5minutes in the lobby to load all of my shaders so that the game wouldn't stutter when I entered a game. It pinned all of my cpu cores to 100% to load it instead of the GPU doing it which is so weird, this is supposedly already fixed in the "vulkan beta Nvidia driver" but who the normal user is gonna fuck around in the terminal to install a beta version of a driver that could easily break something.

While on amd all you need for gaming is mesa 23.1 or above so that you have gpl/graphics pipeline library, and then you can disable the pre caching vulkan loader, then that's it, everything else is smooth sailing already as drivers are already preinstalled, Wayland is more supported on amd because of its open source nature, and games run amazing on it. Best investment you could make if you want to fully switch to Linux as your main operating system ngl.

The only upside to Nvidia is that your new gpu's will mostly work out of the box while the newest amd cards will need to mature for a bit before buying but if you run something like arch and you use mesa git + the newest kernel patches then the experience will get better and better everyday as the drivers mature for those cards

Pop OS does wonderfully with Nvidia nowadays. Check it out!
