I just carried out tests with a Quadro RTX 4000 in egpu but I find that the quality of the denoising is not up to par. While rendering in cpu denoising works well.
first image: render CPU 512 samples and 2 for denoiser
second image: render Egpu 512 samples and 2 for denoiser
I tested with 2000 samples and 0,5 value for denoiser but is not glorious.
for comparison in Iray for Rhinoceoros 3D, 500 samples with denoising are enough to have a beautiful image
Denoising and render pass layers are not yet available for GPU rendering. Coming soon!
ouf, good news 🙂
