It seems from reading the MS site that it can be used to render when no GPU
card is present, and then send the results over the network for remote
viewing. This is probably what the reviewer meant.

Yeh, the MS site also says that WARP is based on the reference rasteriser.
Apparently it is designed to make full use of SSE4.1 and multiple cores.

Quadro FX1700 and E8500.

Yeah, seems plausible. They didn't explain that part...
(Even so, if you're just worried about your PC booting up, it's already
usable over the network. Hmm.)

The review suggests it plain won't work without SSE. But yeah...

Ah.
Isn't the Quadro designed for fast 2D work?

It's basically the same as a normal nVidia card, but they get to charge more
for it:

Well, I do have a machine with an onboard DVI connector. Nothing new
actually - onboard graphics have been around since decades. The
performance is far from the top of the crop of course, but perfectly
sufficient for a Linux-based "render slave" (I don't have a display
connected to it anyway :-)).

What I initially thought when I read the article was that they were going to
put the DVI connector on the mainboard and then have a slot for a 3D card.
The 3D card would then feed the display signal back into the mainboard and
out the DVI connector. That was the only way I saw it possible to allow the
CPU to keep showing a display when the graphics card is removed...

cool, now povray can target the GPU and expect to have a better
performance on WARP! XD

I'm guessing the idea is you can use the video built into the motherboard
and still do fast 3D graphics stuff on it. Most motherboards still come
with a lame graphics chip you can at least get into the BIOS with, and a lot
of the Intel chips come with build-in video stuff in the chipset that uses
system memory as backing store.

They say (at least now): missing *video card driver*.
The video card is ok, but the driver could be corrupted/missing/gone
fishing...
Basically, they do the 3D operations on CPU and use the 2D/desktop
graphic card to display the result. (just like a basic movie player)
Nothing fancy.
Just look what happen when using a GPU at first install (before you
insert the driver CD/download the driver/...): the desktop is working,
but it's not as smooth as it can be. (and limited
capability/compatibility is provided: only 800x600/1024x768/.... no big
1920x1200 yet)
All you need is access to the video-memory, basic setting of ram-dac,
and there you go!
OpenGL in software has been doing that for year.
It's slow, it's ugly, but it works.

It still says this bit on my browser:
"Systems built to take advantage of WARP from a hardware standpoint will be
able to display graphics even when the video card is missing-or toasted."
After reading the MS website, I think what they mean is that even when your
PC has no graphics card *at all*, the CPU can still generate graphics
(including 3D stuff) and pipe the display down a remote desktop connection
or whatever.

They also say "from a hardware standpoint", which would imply maybe you need
the routing to be right for the connector (for example) so that the graphics
card plugs in between, rather than carrying the connector with it, for example.
