I run a NVIDIA GTX 670 with 4 GB of RAM in my MacPro, and it is not flashed. So when I update the system I have to use VNC to sign into my Mac and update the NVIDIA Web drivers and restart before my Mac shows anything on the monitors (or I have to swap my old GTX 270 and do the Update).
This seems to have changed with 10.11.2. In fact it showed the updating screen before the Desktop, and then came to the desktop. Of course it was not normal, in fact all Blue Colors were Orange! I wish I had though to take screen shots, as after the update I upgraded the NVIDIA web driver and restarted and everything was back to normal.
This is awesome news if this continues in the future, as it makes it much easier to upgrade to the latest NVIDIA web driver. I hope it just wasn’t a fluke.
