Hi CatalanGeneral,
I had a similar issue with the last game-jam project. I never quite solved it at it’s source, but this is what I did to fix it:
In your packaged project, open up YourProjectFolder\Saved\Config\Windows\GameUserSettings.ini
Then you can change numbers in the “ScalabilityGroups” section (0-4)
(What was happening in my case is that the graphics settings would get maxed on packaging)
Ultimately the best solution would to be able to package out a project with the Scalability settings pre-set.
Hope that helps!
