hi Guys... has anybody from this scene a Result with a 680 GTX? ... I am guessing 580 gtx is slightly slower and makes in every other disziplines (working with Max or Maya) no sense

thanks! =)

I guess VrayRT doesn't like Lightmaterials with falloffs.

Odd; can you get me a scene for this?

Best regards,

296.10 works fine actually.
I was testing an old scene which had one VrayLightMaterial (which normally works) however this had falloff assigned to it. I guess VrayRT doesn't like Lightmaterials with falloffs.



and this is the error

What kind of issues are you having?

suddenlty having issues with RT after switching from a quadro 5000 to 3 x gtx 580, what's the latest safest nvidia driver?
a lot of people seem to be using 266.58. Anyone using anything later?

It's a pity that it's so hard to find a new GTX 470 nowadays. Buying 2 would seam like the best choice taking into account price/performance ratio.

Quadro 5000, 295.73 driver

Any ETA on this ? Highly anticipated feature as there's no support for multiple lights in preview

[vlado]

I wonder will phx ever be supported in max by rt ?

Only on the CPU...

rt_cuda.dll missing in nightlies....

Does Graphic card memory make a difference? 1Gb vs 1.5GB vs 3GB?

[vlado]

Anyway Vlado do u think that Chaosgroup did a bit of a mistake by investing in to OpenCL mode and not the CUDA giving the fact that ATI Radeons are a failure for GPU processing?

Well, performance-wise there isn't much of a difference - in fact, for us OpenCL tends to be a little faster than CUDA on the same hardware for V-Ray RT GPU. So from that point of view, it wasn't a mistake. On the other hand, it certainly was much more difficult to develop for OpenCL than it would have been for CUDA and we could have implemented the same features much faster. In any, case, see the snapshot below
