It would be related this question(but the question is closed without any solution):
I am planning to do some load tests to UE4 dedicated server. I have built server and client binary and it connected well as expected. But each client occupies large graphic memory and processes many rendering calculations. That makes client heavy on view of CPU and makes inefficient to generate load to server. So, I need to build headless client. Headless means no graphics, no windows.
But I can’t get any information about that. Is there are workarounds for make client headless?
