Historically, it has been less buggy than the open source driver and
much faster, which is why I strongly recommend using the NVIDIA driver.
The NVIDIA driver is at least twice as fast as the open source one, and
usually even faster. The results are similar for older graphics cards.
The NVIDIA driver also supports OpenGL version 4.5, while nouveau is
back somewhere before 4.2 (3.3?).
