I personally think AB3D2 was much worse optimized than any Quake port. But that may be just my problem, because other people have apparently played it on 040 and it ran well (I've never tried patching the game). Quake on 060 with RTG is actually very playable (and a much better game than AB3D2 I might add...).
I like AB3DII, and it ran fine on my 030/50. It was technically advanced -vertex lighting, hundreds of colours, proper 3D, some texture mapped polygon enemies, texture poly's for weapons. More than could be expected on my little machine that could. far more advanced than doom. Considering it gave all these abilities to a humble 030 based amiga, compared to quake needing an 060/RTG shows how well programmed it was.
It just didn't scale well above 030. If it they'd fixed that, and had a decent editor, i'm pretty sure people could have rustled up a quake clone for fast 040 and 060 machines.
