Is C11 using 100% of your EGPU?

Whitesnake
I use my Macbook Pro 2018 with a Asus XG Station X Pro and a Asus Vega 56. During exporting pictures I monitored the activity level of the GPUs: the integrated GPU runs at 100 % and the Vega runs only about 50-60 %. Do you have the same behaviour with your EGPU?

My rendering time went down from 2:52 Minutes to 1:49 Minutes (123 nef-Files with 24 MPx converted to two different jpg sizes), but I'm not sure what I can expect from this setup.

    I found the solution myself: under Mojave you click on the C11 icon and press cmd + I. Then check prefer external GPU. Then during rendering only the external GPU is prefered. The only downside is, that during exporting my eGPU solution sometimes pauses and C11 uses 100% of the CPU. I don't know why the system is doing it. And one other downside is that the other GPUs (internal and UHD graphics) aren't used at all. I think if all GPU units would be used, the result would be even better.

    eGPU in C1 yields unfortunately better results under Win10 than macOS... let's hope that Phase One wizards are hard at work to rewrite OpenCL / create new Metal stack to better take advantage of internal and external GPUs on Mac
