- Well _I_ haven't seen a Falcon either, but here are some points that may be
- relevant :
- 1) You would expect the window scrolling to be slower in true-color or
- 256 color mode, as the computer has to churn through lots more
- screen memory. This is true on any platform, although until
- recently Atari screen modes have all used the same amount of
- memory, making comparisons between modes pretty similar. Remember
- that a bitmapped 768x480x65536 (true color overscan) will gobble up
- 720KB of memory.
- 2) For the normal desktop, you wouldn't really want to run true color,
- you'd use 16 color (which would be equivalent to TT medium,
- 640x480x16, with a larger palette) or 256 color at most.
- applications which require true color, like raytracing, slideshows,
- video digitizers, etc. will be able to change the resolution and
- use the VDI, even if you are not in that resolution.
- 3) Someone a few weeks ago reported that they saw a demo Falcon
- running in 256 color mode, and that it seemed about as fast as
- the TT in 16 color mode. This kind of speed is very good for
- 256 colors (if you've never seen a TT in medium res, with Warp 9,
- it's very fast), especially when you compare it to, say, MS
- Windows. :-) I've seen Windows in 256 color mode and it
- _crawls_ terribly. For a PC you need to buy an expensive
- graphics accelerator or get a completely different bus
- architecture = $$$$.
-
- Don't mean to degrade this into a PC vs Atari war, but Ataris have always
- been fast at video applications, and I don't think the Falcon is any
- exception. :-)
