- theroetical it's 3x1.
- I tried it. Looking to a photo on 640x512 via composite you don't recognize
- much. Looking at it on LORES you can see a bit blockines. If the colors do
- not change too quick blockines is less than on 2x1, as it's smoothed.
-
- could be maybe the only fast way for 24bit animations (for the case 24bit
- games get common. It's quite difficult for cpu to do shading on 24bit
- values, so 8bit will stay for a while).
-
- and maybe it's best way to do 256 color games on a fast ECS machine.
- and maybe conversion time is not that much compared to rendering a
- doom scene on A500 ;)
