> specifically - multiple processors are supported, as is Altivec; What is
hmmm. I'm running IDL 5.4 and I've never seen it use more than one
processor, I should check their website and see what it says. I'm
also not sure just what their altivec support means. I seem to recall
that I can write a simple loop in C code (no altivec) that beats IDL
doing a large array op hands down. I wouldn't really expect this if
IDL was making heavy use of altivec, but I haven't done any real
careful testing. Do they list the areas that have been altivec
enhanced? It seems like IDL should really benefit from altivec. Does
anyone know how well optimized for altivec IDL is? clearly there are
substantial differences in IDL optimization between platforms (eg the
recent Linux vs Windows commentary).
> window buffering? Poor integration with OSX may be an issue but not for me
Roughly, Window Buffering/double buffering = the OS stores a copy (or
two) of the picture in each window, that way the app never needs to
redraw it until it changes. Otherwise everytime you cover it up and
uncover it the app needs to redraw. It isn't a serious performance
issue so much as an annoying artifact that was present in OS9 as well
(and is still present in windows). I get used to the beauty of X and
get frustrated going backward ;)
> not there, and bulging toolbar makes me sick.
heh, the Dock is actually really powerful, you can turn off
magnification, make it really small, and even hide it. I've grown to
love it though initially I too had an aversion.

I thought you could do this in windows, just don't maximize the
individual editor windows. It's not quite the same but similar.
