So we have a mobile game in development and we are able to build/run on iOS/Android and Windows. We run on Windows so some of the team members can quickly see the latest build without having a device and/or the Unreal Engine. However it isn’t a 1 to 1 comparison. To get the windows build as close as possible I would like to run it w/the -FeatureLevelES2 argument. When I do this against the built .exe it says:

Is this even possible?

Thank you for your time,
