Hey Stormrage256,
Here is a tutorial for [Scalability][1], which sounds like what you’re currently looking for. For this tutorial, you’d need to execute console command nodes in addition to the commands from the scalability guide. I’ve also located a [tutorial][2] for you which shows you how to save and load graphics settings using blueprints.
Cheers!
