I tried those setting as you'd already explained them in an earlier post, but honestly it was still way too slow for me. It's just my own personal opinion on OS4.0, if other folk want to give it a try then don't be put off by my opinion, give it a try at least then decide. 
Biggest gripe I have with OS4.0 is Hyperion released it, I bought it brand new, then they only ever released one update for it before abandoning all support for it after only a few months... 
Well clearly you need a 24 bit graphics card too when using OS4, AGA is slow compared to the basic PCI graphics cards for PC. AGA is barely faster than old ISA graphics cards which could never run any GUI that fast.
