- Well dude the problem is NOT the SPEEED but the way how
- the screen is setup!... PC works with CHUNKEY Pixels (one
- byte (8 bits=256 colours/pixel) in your mem is ONE Pixel!
- The AMIGA is using BITPLANES, and that's little different
- one byte into memory means 8 pixels next to eachother in
- just one colour!.. To convert CHUNKEY to BITPLANE your
- processor has to call for memory (for 1 pixel) for about
- 8 times for 1 pixel (256 colours)!!!... And if you have
- a CYBERVISION or PC graphics then it's just ONE memmory
- call!.. So it's at least 8 times FASTER!.... When you
- calculate : DOOMCLONE on Amiga lets take breathless
- full screen on a 1x1 a1200/030+FASTMEM has a speed of lets
- say 3 frames a sceond!!!... When you have a GFX card that
- uses CHUNKEY.. it will be 3 x 8 = 24 Frames A second!!!!
- So... buy a CYBERVISION card and try NEMAC!.... i think
- it works 640x512 in 20 Frames a seconD!.. (NEMAC has special
- routines for CYBERVISION!!.... Soo it isn't the LAMELESS
- coding!.. but it's the HARDWARE!!!.....
