I’ve read about the Steam Deck’s upscaling settings, and it’s pretty promising, more than sufficient for my needs! I didn’t know you could use linear upscaling through the QAM menu without a performance hit, definitely worth trying. Thanks for the detailed info!
IMO Organic Maps. I’ve used it for years now and it just works and it has a great offline navigation (you can download the areas). Contributing to OSM through the app is quite easy too, so you should consider contributing the places you often visit that are not yet on theap, it helps the community too :). For some places I couldn’t find I’ve used Apple Maps to get the coordinates.
