The old denoiser often doubled the render time and with the new OIDN it seems to more like about 10% increase.abstrax wrote:The denoiser itself probably won't get significantly faster and that rendering itself slows down significantly if you use the AI denoiser is due to the additional data it requires to do the denoising, but this is very scene dependent. The new Open Image Denoise mode should improve the situation though as it is only calculating 2 additional AOVs and thus the additional overhead during rendering is reduced a lot compared to the AI denoiser. At least it should be. If you have a scene where this is not the case, please let us know.coilbook wrote:Can we get a faster denoiser? Rendering times increase by a factor of 2
Viewport is also a lot more responsive with the new denoiser while it was really sluggish once you enabled the old AI denoiser.
