They were so good that a multiple times computationally slower Motorola processor would run a Doom clone at the speed comparable to a contemporary PC bucket. Never. You just could not get a VGA-on-i486 level rendering performance out of 256-color AGA fullscreen, even with Motorola 68040 on the Amiga 4000. All the fast 3D demos and games I saw were partial-screen, with 2x2 pixels, or both. Good-looking ones were slow. An example with at least some commercial success was Alien Breed 3D. Check the video here: https://www.youtube.com/watch?v=ksQG8vnvlpg https://www.youtube.com/watch?v=ksQG8vnvlpg Because it was so hard to do per-pixel rendering on Amiga all these 3D graphics demos and games on Amiga basically concentrated on delivering the graphics only, with shallow content and amateur-grade playability. Doom had a lot else going on despite the smooth graphics, and that actually made Doom a good game.
