- There is no solution to the problem you're having. Anytime you move the
- camera in an animation the speed will bog way down. The reason is that rather
- than a reference image and a small amount of data on how the picture changes
- over each frame of the anim you have a reference frame and a LOT of data
- about the changes from frame to frame. Since the Amiga can only move data
- into the display chips at a set rate, when you have more data per frame you
- will have less frames per second. If you have a FAST (40 or 50 mhz) 030 in
- your machine or an 040 accelerater you can get somewhat better speed by using
- CPUBlit. This makes the 030 do what the 7 mhz 16 bit blitter would normally
- handle.
- A better solution would be to buy a 4000 with a 32 bit blitter and a faster
- bus. Of course this option is a little more expensive.
