There was a really interesting thread on another forum about C2P and DOOM speeds on different Amiga systems. I tested it myself on two of my Amigas, running the DOOM Benchmark, and these are the results I got:
A1200 030/50Mhz 32Mb (Optimised 020 C2P) - 8481 realtics (8.8 fps)
Amiga CD32 68020/14Mhz 8Mb (Optimised 020 C2P) - 18971 realtics (3.9 fps)
Amiga CD32 68020/14Mhz 8Mb (Optimised Akiko C2P) - 12872 realtics (5.8 fps)
I hope this helps clear up some peoples ideas of exactly how fast each of these CPU/C2P combinations are.
The bottom line I guess is this: Akiko DOES work, and DOES make 3D games run smoother (if it's utilised, obviously), but the increase isn't drastic, not as much as adding a 030 at least. I have not tried to run DOOM on the CD32 without Fast RAM (I have a SX32), and I'm not sure if it's possible in only 2MB Chip RAM, but if someone is willing to try writing a startup sequence or something to get it booting, I'll gladly give it a go and report how a CD32 runs the game using Akiko WITHOUT Fast RAM.
Oh, and obviously the Akiko routines for Shapeshifter and Fusion wouldn't be great on a standard CD32, but they might help out if you have a SX32 Pro 030/50Mhz with 32MB RAM or something, with slightly faster screen updates it might be alright to run some older 2D games in colour. Maybe
