- Unfortunately, quite a few netters writing to the Mac newsgroups start to
- insult other folks as soon as they think that the other one got something
- wrong. Why don't you just spend that wasted energy on fact-based discussion?
- So, back to the topic, here's what I'd say about the "VRAM case" :-):
- the VRAM itself does not slow the machine down. However, the speed of the
- machine depends on the color depth that you're using: The more bits per
- pixel the machine has to deal with, the slower it gets, since the Mac still
- uses its main processor to look after what's happening on the screen. If you
- compare b/w mode with 8-bit color, you'll definitely notice a slight (!) loss
- of speed, when the machine is manipulating the screen output. If, however,
- the Mac is simply doing some numbercrunchung without much visual output, the
- speed will not be affected by the color settings.
