Earlier quoted context omitted.
1) I have NVidia RTX 2060 in my Linux laptop (Lenovo Legion) and NVidia RTX 3070 in my Linux Ryzen desktop. Previously had 1060 in Intel Linux desktop. Zero issues.
I'm on the same boat, however, it's a bit unclear if parent is complaining [also] about their open source support. Their antagonistic position towards open source (AFAIK there's no comparison to AMD Nvidia open source drives) is a big issue for me.
Which support?
They have an official closed-source driver. That's what they support.
Parent is complaining that when they run an unsupported third-party driver, it doesn't work as well as the actually supported driver.
I think these distinctions are important, becaues NVIDIA is not telling anyone that they have (1) an open source driver, and (2) that this driver is well supported.
Their supported driver works great.
OTOH AMD does have an open-source driver that they support. In my experience, this driver works much worse than NVIDIA's proprietary driver. You can't use AMD GPUs for compute, etc.
At the end what this means is that users currently have to make a choice. Do you want a GPU driver that works well, or a GPU driver that's open source?
I don't like to have to make this choice, and every individual weight these values differently.
