The CPU and CHIPSET slider doesn't work how I thought it might. It is unusable for this game.
Standard A1200 config.
030 without JIT or FPU
Fastest possible CPU but maintain chipset timing
Instant Blitter
I get 19fps in full screen (press numeric enter) at 1:1 (as reported by the game, WHDLoad tool type CONFIG2=1)
Looks about this speed :

quite playable, but not great.
It's a real shame the code is such a mess, a lot of other 3D games on the Amiga scale quite well. I guess if it could have been fixed, it would have been by now.
I always thought it was a great feat of coding though: some 3D enemies,3D weapons, hundreds of colours, full 3D view, I think it even has some pulsing vertex colours at some points. Not bad to get all that on an 030. It many ways it was more advanced than doom.
