ATI Demos on nvidia cards?

nVidia supports packed MRT. I can't remember the maximum 'packability' though...

If that's what I think it is. . . it requires NV_fragment_program to pack multiple values into a FP32 register and output the result to an offscreen, 128 bit render target. A second pass would then be required to extract and render the data. Depending on how the packing works, it's possible that the result could be used for displacement mapping, as OpenGL guy was implying for MRT, by using the data as an interleaved vertex buffer. However, one can only pack two FP16 values or 4 FX8 values. In either case, the result is much less precision and dynamic range than what is possible with MRTs.

Actually only the 4 FX8 version is supported by the D3D9 API...

In OpenGL you can mix-and-match render targets with that packed format (so one FP16 and two FX8's work).

Btw why can´t you download NV35 demos yet!?

nVidia's demos have never been available immediately after they showed them at various trade shows. It may be a little while yet, though certainly before August-September (when the next products will be launched).

Eh? nForce3?

My guess is that they want to put in some security systems in to prevent ATI users to get Dusk, eh. They *are* very unhappy of that whole ATI Dawn stuff, you know...

Hmm, I'm wondering if a nForce 3 even exists... I remember nVidia saying the nForce 3 ( not only the 3 ) will mostly be workstation stuff.
So maybe they're directly going to nForce 4 or *gasp* switching to Intel? I'd be surprised to see that so early, though, and without any leaks.

Isn't nForce 3 the Opteron motherboard? In which case it is definately server only.

nForce3 is for Athlon64, nForce3Pro is for Opteron
