V-Ray Settings on a new MacBook Pro

Hello, I understand that for maximum rendering performance a PC with NVIDIA cards is the way to go. But I am a Mac guy and also on the move a LOT, so I just purchased a new 16” MacBook Pro

2.4 GHz 8-Core Intel Core i9
32 GB 2667 MHz DDR4
AMD Radeon Pro 5500M 8 GB
Intel UHD Graphics 630 1536 MB

I have been trying to learn if I should just leave the V-Ray settings on CPU, or if I would benefit from switching to the CUDA option? When I select CUDA I see the the following choice “C++/CPU on Intel® Core.” Is this a selection or should make, or just leave it on CPU

I really don’t know what I am playing with here, so looking for guidance from those wiser than me.

Many thanks!

I don’t know especially about Macs, but I understand that CUDA and RTX are technologies that work only with Nvidia graphics cards.

@Anssi is correct. Apple stopped using NVidia graphics maybe 5 or so years ago and all recent models use either Intel or Radeon graphics. V-Ray requires NVidia’s proprietary CUDA architecture for hardware acceleration of rendering. So on all current Macs you can only choose CPU-based rendering in V-Ray. It works fine, it is just slower.

Thanks so much for clarifying. 100% CPU it is :+1:t3:
