Hello,

I have an eGPU up and running for my Mac.

Now, I want to enable it for UE4.

I have tried to enable the Prefer External GPU option in the UE4Editor app info, to no avail:

In Preferences, I see the Show Editor GPU Selector setting disabled by default. I enabled it but I don’t know where to look in the Editor to find the GPU Selector:

Thank you TAKA, when I use Radeon RX Vega 64 on my iMac with Sonnet Breakaway 650, the Unreal is very slow, do you have this issue on your Mac?

Bumping this thread. I’ve enabled the “Show Editor GPU Selector” and restarted, but the GPU selector is not visible anywhere—even where you have suggested with your screenshots. This is the case for UE4 and UE5(Preview). Any ideas where else I should look?
