Vray not using GPU

Vray in Rhino is not using my GPU at all, have looked at settings etc, any advice ? tia
running V6 Rhino, Vray 3.6, Quadro P2000 GPU

did you get any resolution on this? I just got a new computer and it doesn’t seem to be using the gpu at all…

unfortunately not :frowning:

I reached out to vray support…ill see what they say.

There are very few details posted, and I’m not able to “guess” what is going on. For instance, how exactly you determined that the GPU is not used ? Did you render on the GPU ? Did you get an image out at all ? What about the message log ?

More circumstances, please

Hi Nikolay, I rendered in rhino 6 using the vray next plugin. I had it to the GPU option and I had the task manager performance open, so I could see that the GPU was not being used above 5%. Also, I ran the vray benchmark and got a very poor score. I need to fix this so i can use the GPU horsepower as it’s meant to be used.

@PeterB is that 328 score with or without using your Ryzen? Seems it is without. I get 81 with a M4000 so yours is about 4x as fast, which I think is normal. I don’t think Vray is using the raytracing cores yet.

Tested here - the problem is the Windows taskmanager. I get 10% usage there, but the free tool GPU-Z shows me 98% GPU usage.

It is not the task manager that is the problem, but the wrong metric.
One must specify “cuda” or “compute_n” to see more realistic load:

Thanks G. Yes, it’s without using Ryzen. I guess I expected more when I compare to the scoreboard.

Ahhh now I see it. I noted that the cuda graph is flat with vray but dances when I initiate a raytrace mode. Interesting…

Will give this a shot. Thanks.
