While I don’t know much about video cards, the IBM Monochrome Display Adapter (MDA) is often called the first video card and had a couple of contenders for first that were either designed earlier or released at almost the same time in 1981 and were all for displaying text only. The first GPU card sold to the public was the GeForce 256 in 1999. I’m assuming there’s some in between that were not really used by the public that would have been used in movies and whatnot.

The reason why nobody was selling GPUs before Quake was because quake was THE first 3D game. Doom and other games before Quake were 2.5D and didn’t have 3D models only sprites. Games before Quake essentially mimicked 3D while Quake IS 3D

I’m fairly certain that the left one is Combat Evolved

I’d argue that quake did far more for 3D graphics then it did for FPS. Like Doom is what got FPS into the spotlight even though Wolfenstein 3d came first. Like quake is pretty much what made real 3D possible and doable on the hardware of the time thanks to everything going on under the hood
