I have a Dell Precision 7720 laptop that has both the integrated Intel HD Graphics P630 as well as an 8GB nVidia Quadro P4000.
Thru the nVidia control app, I've got my machine setup to run on the iGPU whenever a non-CAD app is running but once I launch SolidWorks, the Quadro spools up and automatically takes over. When I toggle between various open apps, the GPUs switch back and forth seamlessly. I don't know if that's the info/answer you're looking for but I hope it's helpful.

Hi Eric, thanks for your info. That is another situation that is good to know. My main concern is if I get a untra-portable with only Intel iGPU and install SW on it. If later on I add an eGPU, I wonder if I will need to reinstall SW all over again or the software will act according to whether or not I have eGPU connected.
Glad to be of any help that I can. In the case of my setup, the nVidia control panel is what is being used to tell the laptop which GPU to use for each particular application so I'd expect the same type of control from the eGPU (although I must admit that I have no experience with an eGPU so your mileage may vary ). I wouldn't expect that you'd have to reinstall SolidWorks - after all, we don't need to reinstall it when we update our video card drivers to the latest certified version.
Anyhow, again, I hope this info is helpful.
From my experience SOLIDWORKS will run on most things.
Whether it has graphic issues are highly debatable and can have great variations.
I have SOLIDWORKS running on a HP Spectre. It is not my main work computer and I it use mainly for testing and not much else
RealView doesn't work with Non-Approved Graphic cards because they are not listed in the Registry, but is a simple process to setup
