Still don't know how to use them correctly. Some questions: 1. I see I can select 1080p and 4K in the same time for the same game. If so, which one will be used? While game is running in Settings > Graphic Packs both of them are tagged as "yes" in the "Active" column, so it doesn't help to understand. 2. Does it make sense activating 4K while using a 1080 monitor? I'm asking because maybe downscaling can give some visual improvement in terms of anti-aliasing, don't know.
