Render is super slow/rhino crashes/computer issues?

Hey everyone,

okay so basically it took 8h+ for my render in draft quality and 72 DPI to finish to 610/1000 - essentially what I wonder - 1. what possible settings are there that I dont know about that might speed up rendering time 2. Well I already know my computers RAM capacity: 8 GB is not great but what specs (in a macbook) is it that affects up rendering time?

Apart from this Rhino has crashed a lot while Im working meaning its bit of a no brainer to just buy a new computer, because i guess that has nothing to do with anything else than my computer? Im not running any programs at the same time or even in the background so I think its just my computers pure capacity thats failing?

Hello -

Please run the SystemInfo command in Rhino and copy/paste the results here.

Thank you, here it is:

It looks like your machine is at least 8-9 years old - I don’t know what is supported, but I would see if you can get a more recent version of the Mac OS - that said, I do not think it will ever be very fast. It might be worth trying the legacy renderer (Render menu > Current renderer), I don’t know.

Thank you!

Ill try that or buy a new computer.

Thanks

Hi! I have a Mac Book Pro from 2019 but I find the rendering still very slow (RAM capacity of 16GB). I think a PC will do better? The program Rhino is originally made for Windows and perhaps the version for Mac is still not compatible? Just made a render → 50 samples, good quality, this took the program 3 hours and the image isn’t even of a good quality. Moddeling in Rhino 7 is great, but the rendering is taking way too much time, or is this normal? Also the draft renders make no difference still very slow.

Drawn a simple white block, turned the render on, selected good quality, size 800x600px, 50 samples → takes 2 min. (no environments, no lights etc.) See attachment.

Hi @kim3

CPU based rendering will be that fast with the default settings and your simple box set up… I have a similar Mac here and get around 2 mins with the same image size.

There are two things you can do though in Rhino 7 that will help speed things up. Use the command PackageManager and install the “Intel Denoiser” and the “ProRender” plugins. They are both free and will really help here. The denoiser removes grain as a post effect so that you don’t have to get to as high a sample count. Generally between 50 and 200 samples is good and then denoise it to remove any grain in the shadows. ProRender on the other hand is a different renderer, switch to it in the Render drop down menu > Current Renderer flyout. Then run the Render command again on your simple box set up… it’ll probably be about 2 seconds for the 50 samples. ProRender will use your AMD GPU for the raytracing instead of the CPU.
