So this is probably something that only affects a small number of us, but it seems that Aspyr doesn't support eGPUs for Civ. The previous update pushed Civ beyond what my old Mac's weak GPU can handle. I purchased a nice eGPU that runs everything else perfectly, but not Civ. I've put thousands of hours in this game and am super sad that I can no longer play it. Say what you will about Macs, but my old machine is still in excellent shape aside from the GPU. So I'm hoping against hope that there is a plan to make eGPUs supportable. Thank you!
