Framerate just got a nice boost using latest version of cosmos 68060 library. (From 11.2 fps using P5 lib to 13 fps using cosmos).
It's quite playable with my Blizzard 1260/75Mhz now.
I had my card underclocked 5 mhz because this is expensive hardware and it felt I was pushing the card too much.
Anyway, here is how it runs now.

Keep in mind this is running under 20 year old AGA.
