Denoiser speed

[fraggle]

Hello, just play for the first time the denoiser.
The result is incredible in terms of quality but the time to for the Denoiser is 10 time more than the rendering!
1 frame 6.5s for the rendering, total 1min6s for an 1280x720 px.

Is it normal?
thanks

If you have a good GPU the denoiser can be a lot faster. Also, it will be the same denoising time regardless of the actual render time.

Thanks, has it something to do with this warning?
I do have 3 GPU, but sounds like they can't be found.
Where do we setup GPU denoiser in the vray setup?
Thanks

Seems that the setup is correct but the GPU are ignore.

[vlado]

What kind of GPUs are they?

Best regards,

Gtx780 / gtx780/gtx670

Seems that the problem spread all over the feature using GPU in the VFB.

We tried to replicate the issue on similar GPUs but we didn't get any CPU fallbacks.
What are the drivers version on the GPUs, if they are not the latest ones would it be possible to update them and see if there is any improvement?
Same thing for V-Ray, if it is not 3.50.04 please update to that version and re-check.

Are you able to see the GPUs in OpenCL device selector tool or in RT Render Devices select rollout?

Does the issue occur on every scene or just on particular ones?

Solved by installing the up to date driver.
Thanks
