- A while back I said that bit-plane modes are better than the word-per-pixel
- modes, for speed of sprite drawing, and TrueColour (word-per-pixel) would
- be best used just for title screens. bzzt - I was wrong.
-
-
- I did some calculations and coding on the weekend, and it turns out that
- TrueColour (word-per-pixel) is actually VERY good for games. I expect
- that a game using the Falcon 320x240 truecolor mode will be around twice
- the speed of the same game written on an ST using Low resolution, simply
- due to the CPU speed. And a LOT prettier (65536 colours vs. 16).
-
- ie. drawing sprites in TrueColour is as fast as drawing them
- in 4 bitplane mode.
-
- Plus, sound processing will have a MUCH lower cpu overhead on the Falcon,
- so games will gain speed there (and sound a lot better!)
-
- The reason why TrueColour is so good for games is that no shifting is
- required, plus only the area actually drawn on needs to be accessed (and
- hence stored for wiping purposes).
