you can patch your executable to get it running on a geforce, check this: http://forum.beyond3d.com/showthread.php?t=54724

Sounds like SLI or quadro is needed shame, i get 4fps at work on a quadro fx 1700, wonder what my overclocked gtx 260 at home could do….

Worked just fine for me with SLI GTX 260 Core 216’s. I just downloaded the demos and ran them (this is with the 190.62 drivers of course)

I can’t run them on my GTX 260c216 either. 190.62 drivers!

Yeah, i’m agree with CoinCoin ; By the way, in a cup of years, GPU will be deprecated and all renders will be done in ray tracing by CPU’s.

But i would like to see that in motion ; unfortunatly i only have a GF4. Could you post a video ?
thanks !

I’m disappointed. Doing real-time ray-tracing on procedural spheres and planes does not require a graphic card ! I was expecting something more impressive from NVIDIA. This is at best a tutorial for Optix programmers.

Looks like the next Marbble Madness will looks amazing, though requiring a 200 W bleeding-edge GPU of the death.

I’m just kidding. This sure let us expect some real hot stuff in rendering in the upcoming years. Demo makers are already using GPU ray marching a lot, especially in 4k intros.

OK thanks a lot !
I was thinking that the demos may be just looking at the device name string to find “quadro” in order to accept running. But it don’t seems to be the case since your geforce is well recognized as geforce by the system. NVIDIA must have another internal way to detect quadros.
Maybe it’s because it’s a dual GPUs card…
Badly I didn’t find any way to make the demos running on my card

Whatever, thanks for your help !

PS: I have seen the Turner scene demo at Siggraph, and I didn’t find it so impressive, it seems really slow to me, especially only for tracing two procedural spheres and a plane !

I hope this will help you ;)

No, I was thinking of NVIDIA control panel “System Information”, or windows device manager.

where do you see that name? in the command line output?

By: Cyril

Cyril — Thu, 27 Aug 2009 13:05:12 +0000

It seems so because I can’t get them running on my GTX280. Could you take a look at the device name provided by windows ? Is it indicating “Quadro” ?

then i hope its the drives, if anyone else tries and can pseudo-confirm anything i’d apreciate when i update drivers this afternoon i’ll let you know though

By: JeGX

JeGX — Thu, 27 Aug 2009 12:59:42 +0000

I did nothing special, just downloaded the demos and ran them. Maybe the GTX 295 is recognized as a Quadro, I don’t know…

By: Cyril

Cyril — Thu, 27 Aug 2009 12:55:20 +0000

Thanks,
I am interested to know how you bypassed the test for quadro board ? Is changing the device name enough ? How did you do it on windows ?

By: JeGX

JeGX — Thu, 27 Aug 2009 12:54:22 +0000

Yes try the 190.62 and let me know.

By: Jose

Jose — Thu, 27 Aug 2009 12:52:48 +0000

I guess it might be the drivers, but mine are 190.38 which isn’t that old If anyone has other idea im listening, otherwise i’ll update drivers when i have a bit more time.

By: Jose

Jose — Thu, 27 Aug 2009 12:49:38 +0000

You ran them on a GTX295? I can’t on my 260, the command line window says no quadro fx detected :/
