Doom was “real” 3D in the sense that it displayed proper 3D environments with textures and all. You could go forward and backwards, left and right, and up and down of stairs/elevators. That’s all 3 dimensions.
The player might have technically been confined to a 2D plane, but I would say it’s 3D graphics.
But games with proper 3D movement came much earlier. One example is Elite from 1984, which allowed space flight with full 6 degrees of freedom.
Another example earlier than Quake worthy a mention is Descent from 1995.
Decent is far more 3D than Quake in that it’s play area goes in all directions. However I think it gets overlooked because I think it owes as much to flight sims, and those have been 3D for a very long time.
