Is it possible to set the screen percentage through the game user settings rather than by executing a console command?
It doesn’t look like it. You can see in the whole UGameUserSettings class that Screen Percentage is not one of the options.
However, there is the FQualityLevels struct property called ScalabilityQuality. Inside here, there’s resolution quality (and various other scalability settings). This isn’t exactly the same, but this other AnswerHub Question has more details on the difference between the two.
Hey, thank you for your help.
