So post some Frames per second benchmarks of Doom running on your machine, and what hardware the machine is using

I'll start it out:
Using Doomattack, with screen size two steps below max.
High detail 10-12 FPS
Low detail 18-20.
They both fluctuated a fair bit of course, but those are pretty average.
This is on my ACA 030/56 from Individual Computers, and plain old AGA.
