Alright I’m back.
First of all, do not apply scalability, instead you should be using “apply settings” and “save settings”
well that is the case for me in 5.3
And then, most likely in you game instance blueprint off of Event Init you call the “load settings”
Lastly, Scalability is a pre-defined set of Cvars and calculations based off hardware. These are not found in your project but rather Engine install location. Under Config you should find a bunch of .ini files all starting with “base” i.e “base scalability.” this houses those predefined values.
In this example I set my shadow quality in menu and when I change the setting It will apply and save on change. But if you have a save settings button instead you will want to use the “save settings” there. Same if you were to have a button to apply the settings. Just don’t forget to “get game user settings” and plug that into the target.
Let me know if this helps
