Ah, floating point no's are around 3 to 4 times slower then integer when compiled, but so what? My James Bond game uses a lot of floating point stuff and that runs fine, if it didn't have to contend with the blitter's speed it'd run at 50fps ;).

If you want the game to remain at the same speed, add an automatic frame skipper, and store stuff like sin/cos's in a table instead of calling them directly.

See ya.
