Hello, I am using High Sierra with eGPU and while it works, the performance is really bad, everything is lagging.  I assume it's due to eGPU powering both screens - internal and external. Is there a way to force MBP to use 750M for internal screen and use eGPU for external?

When I look at About I see that 1080 is powering both screens. 

However in Graphics 750M is shown to power Display. What should I believe? 

 

I have MBP2013 750m + 1080GTX @ Thunder2 / 10.13
