I've gamed since 1979 and have used nVidia on Linux since the early 2000's...without issue.

There have certainly been issues (I've been on Linux with mostly nvidia GPUs since 2004) but it's almost always been caused by the module being outside the kernel, and a kernel update breaking compatibility sometimes, understandably. This has always been fixed quickly on nvidias end though. And early Wayland issues and the current DX12 -> Vulkan translation performance issues in more recent times.

But overall I've also had a mostly stable experience during that time. New hardware is supported mostly at release. Not always supporting all the latest features straight away mind you, but still. Meanwhile I seem to hear about issues with support for Intel and AMD cards at release frequently in comparison.
