I don’t have the stomach or space for a whole new PC build… and I like the idea of an eGPU. How well do these work with VRAY? I guess unlike some other use cases, I don’t need to drive the main display from one of these. I just need it to render. Any thoughts from Chaos group? ---

There has been talk about that here for a while. I, too, have looked into it, and the talk never really goes anywhere. I’ll follow along to see if anything has changed. ---

Using eGPU is supported with V-Ray GPU, you will be getting near 90% of the performance on high-end GPUs Find a box that supports Thunderbolt 3 at least, then plug and play. Your motherboard or laptop needs a Thunderbolt 3 connector as well Don’t connect monitors to the external card We have a similar setup at the office, we will be able to provide you support for this setup Best, Muhammed ---

When you say performance is 90% - where does that manifest? Even if I use the eGPU as a second card for rendering, and not updating the screen? ---

90% is comparing running the GPU through Thunderbolt, to using the GPU natively at PCIe with eGPU you shouldn’t connect the external card to monitors, this will lead to issues ---

There is another thread with more detail, but Ive been using a 3090 in an external dock with my Razer laptop for 6+ months with no issues whatsoever. I dont really monitor performance, but Im rendering many many interiors.
