denoising cpu

[celmar]

Hello!! usually, i use "high quality denoising" as set up... As render farm asn't graphic card in its computers, what woul be the best denoising with the processor???

High Quality Denoising does use the CPU, it's the Corona denoiser :) The other two (Intel and NVIDIA) are GPU based - NVIDIA needs NVIDIA cards, but Intel should work on most cards.

thank you, Tom! shame on me, I was sure that the high quality was based on teh graphic card! good new, if it is based on the processor!

The Intel AI denoiser can also be used without a GPU for production rendering. If no GPU (or no supported GPU) is detected, it will automatically switch to CPU denoising.
IR denoising is always done on the GPU.

Maru, if the Denoiser switches between CPU and GPU in a mixed render farm or Team Render setup, is there a risk of flickering with different noise patterns? Just curious.

The Intel denoiser running on the CPU and GPU should produce identical results. On the other hand, the AI denoisers are not recommended for sequences anyway as they don't have any kind of temporal filtering.
