As far as I know, Descent really wasn't 3D. It uses (pretty much) the
same ol' tricks that Doom did to create pseudo 3D worlds. You'll also
notice that in descent, the characters are actually 2D sprites.
In Quake everything is totally 3D (except the fire) and has dynamic
light source shading. This takes up a large ammount of processor time
because of all the calculations that must be done to render one scene.
And the characters in Quake are totally 3D too, which means even more
polys to render.
