While it is true that running an NV card in a VM is no longer an issue, if you're serious about Linux gaming, stability and compatibility AMD is the way to go. If you already have an NV GPU you by no means need to go out and buy an AMD GPU to make things work. It's just that you'll run into far fewer of what I'm going to call "unnecessary errors." This is even more true if you have an APU with an nVidia GPU, you'll get driver conflicts. I've never seen an "unnecessary error" that wasn't simply solved with a restart, but the fewer restarts the better.That’s no longer something you need to worry about now. NVIDIA supports running GPUs in a VM without needing to use workarounds.
