I have been experimenting with overclocking my FPU (33MHZ rated). Running Quake on my Falcon I had problems using the FPU@25MHz when CPU was still at 16MHz. Perhaps it was just Quake or the fact I was only using version 1.06 of the PAK files? I didn't try it with any other apps, just trying to find software I need that takes adavantage of the FPU. I know things like POv, Neon and so on use it by I don't really need to use them.
