Crysis with no GPU? Now I've seen everything!

"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."
So what are they going to do, put the DVI connector on the motherboard or
something? Sounds cool.

Looks like this is just a beefed up version of the reference rasteriser that
comes with the DirectX SDK.

I guess the idea is that if the GPU is toast but the card itself still
works, it's still usable... but wouldn't that be the case anyway? *shrugs*

Beefed up to support all DirectX 10.1 features, yeah...

But how is it going to work if the entire video card is "missing" like they
say?

The reference rasteriser already supports all DirectX 10.1 features, that's
the idea of it, you use it to test/check that your code/GPU combination
produces the same output as the reference rasteriser to rule out any weird
driver issues. I have the DX10 reference rasteriser here from the March
2008 SDK. Amusingly I just tried it on one of the samples, 20fps on the
GPU, 0.2fps on the CPU :-) I guess they made it a bit faster :-)

Doesn't make any sense to me either. Maybe the reviewer got their facts
wrong?

So I'm guessing it's coded for correctness rather than speed. If that's
true, there's probably a few easy ways to speed it up.

Which GPU? Which CPU? ;-)

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...
