Can I utilize my 2 GPU's?

Development Getting Started & Setup

**Hello and please, excuse me if this is not the right place. So I have read the topics in this forum and some on reddit too, but couldn’t resolve this for myself. I have 2 GPU’s. MSI RTX 3080TI OC and GIGABYTE 4070 OC both 12GB of VRAM. Is there a way to use both of them in Unreal Engine while working? I mean when I enter UE I’m using only the card that is connected to the PCIe 4.0 slot which is the 3080TI the other one is at idle. I know that they are not SLI. So I guess my question is can I utilize my both GPU’s which are non-SLI? Thank you in advance! **

Hi Stormmiee,

Unreal Engine can only utilize one graphics card at a time.

Also, It looks like you should be able to choose which GPU UE uses in the Nvidia control panel.

I understand, okay, thank you very much for your reply!

UnReal does support multiple GPU. Just not an external and internal together. You find details on YouTube: https://www.youtube.com/watch?v=Io6oSCYkLg0
