multi-GPUs performance

[furettolov1]

Hi everyone,
I want to export a "very long" interior video, something like 5-6 min.
In this moment my work stations have an rtx 3090 and with 800samples takes 2 min for each frame (a lot of refractions/reflections)

I'm thinking to use a render farm like Igpu where I can rent a server for some time, I see that they have different configurations.
How many gpu are supporterd in Vantage? can I use 8 GPUs?

Anyone know the performance scaling releted to different number of cards?

Best,
Alessandro

Vantage is currently limited to 2 GPUs. It's a real-time renderer so it works differently from V-Ray GPU. Can't specify exact performance when adding a second card because it depends on multiple factors. It's best to try it out for yourself if you can.

I suggest... If you plan to use 2 GPUs. Then it is better to choose two identical，Or use the one with better performance as the main GPU. RAM Don't be too different.
