Denoiser on CPU path

Post by Asticles »

Hi,

I'm getting very different denoise results with cpu, compared to opencl gpu.

It seems that is something related to pixel intensities, because clamping on cpu helps, but still you get worse quality.

Path cpu:

Path opencl:

Can you help me with that?

Thanks

I don't know it's tragicomedy vs just bad to me... If you have some nvidia gpu you could try that standalone denoiser.

It's important to me because if I get rid of memory on the gpu, I need to switch to CPU without fearing this.

Yeah, I'm currently using optix denoiser.

Mmm, do you have 2181 light source in that scene ? And default light sampling ? And a path depth of 10 ? You must have a LOT of noise without the denoiser even with 350 samples :?:
