Rendering time extremely slow

Dell Precision 5530 laptop.
i7 processor
16 gb memory
NVIDIA Quadro P1000 graphics card
Rhino 7

I am having trouble with my rendering times taking close to an hour for a fairly simple piece of furniture. I have contacted both Dell and Rhino support. Dell told me trying to upgrade my memory to 32gb may help but Rhino told me that it would not and that it’s most likely my graphics card.

I have checked and Rhino is using my GPU and not my CPU to render. I also read on her to try to change the tile cycles and that has not worked. Can someone help or do I just need a new graphics card that actually results in just buying a new computer?

Hi Emily - close to an hour for what exactly? Finsihing 50, or 100 or 1000 passes, or? Are you waiting for all passes to be done, or waiting until the image looks good? They may not be the same thing. You can get away with far fewer passes in general if you install and enable the NVidia denoiser as well.

If you cannot sort it out, please send the file to with a link back here in your comments.


Thanks so much for your reply.

I am somewhat new to the 3D world so the verbage is confusing to me. By passes, do you mean samples? If so, I am waiting until they are completed, and the number is 1500, final quality. I have installed the Post Effects NVIDIA denoiser but I do not see a difference.

Ok, just used the Denoiser properly and it made a huge difference!

Hi @Emily_S_Warren

I’m sorry to say, but the P1000 is not a great card for GPU rendering - it has 640 Cuda cores, and was an entry level card even when it came out 4 years ago. The entry level RTX 3050 from the current generation of cards has 4 times as many cores. It’s sometimes a little depressing how quickly hardware is made, if not obsolete, then at least subpar.
The denoisers are a great way to get better results much faster. You should try both (not at the same time, obviously!) the Nvidia and the Intel denoisers - the give sligthly different results and you might prefer one over the other.


Additionally the Nvidia denoiser uses the GPU, putting yet a bit more stress on its resources. The Intel denoiser works on the CPU, which in some cases may be the better choice resource-wise.

Thank you. When I purchased the computer, I was only running autocad and photoshop so the graphics card was not a huge deal. I’ll know better next time!

I’ll try the Intel Denoiser, thanks!
