Windows NT provides to ways for applications to run on any particular CPU:
* Intel emulation for x86 binaries.
* Native code.
Any Intel win32 binary will run on any NT supported platform (provided
the emulation subsystem is installed) on any RISC processor. You take
some speed penalties because of the emulation. Mostly, this is a good
way for you to be able to run random Windows productivity applications
and utilities that don't have native support for your RISC processor.
My impression is that some of the faster RISC systems emulate a 486
with decently snappy performance, so this isn't too bad an option for a
lot of things, especially if you have, for instance, a dual MIPS
Deskstation machine.
To get full performance, you need to run an app that is compiled to the
native code of the processor on which you are running NT. This means
that the application vendor needs to supply you with the appropriate
executable binaries for your CPU.
You can probably expect to start seeing apps that ship on CDROM with
several binaries and a smart install that will select the appropriate
one for your machine. Either that, or you'll find yourself specifying
in your order which CPU you are using.
Supplying binaries for alternate processors is (in theory) a relatively
minor incremental task for the developer, so you'll see more and more
of them doing it, especially people who make high end graphics tools
and the like. The big problem is distribution and all those potential
SKUs and the ensuing confusion. CDROM and smart install programs will
probably go a long way towards solving that. If your particular vendor
is late delivering native support for your CPU, you should probably
blame their compiler vendor before you blame them.

Thanx for the reply Michael!
Okay another question..I just called DEC and got a whole listing on
Windows NT software that will work on their machine..Sure, enough Real 3d
is on the list..Now here is the qestion. If software says it runs on
windows NT machines...are there specific versions for each type of
windows Nt platform? or just one version? Will Real 3d for windows Nt
running on a DEC Aplha take as much advantage of teh cpu power as real 3d
running on windows NT raptor system??? I know thes eare not really
lightwave related..but soon...we may decide to look in to these new
systems for lightwave...since it may come for Windows NT...Also, will SGI
box's run NT??
