When you realize how many loading screens there are, you begin to understand why Bethesda requires SSD versus HDD, otherwise half your time would be spent on loading screens.
Unfortunately, I haven’t found anything within the realms of “vanilla Starfield” to remedy your issues. I just kept playing through the main quest and as time went on, it got better (in my opinion). It’s one of those “oh you have to slog through X hours before it gets good” type of games.
Outside of the above, I can only recommend shelving it and waiting for mods or DLC that may freshen the experience.
I think the biggest single factor they point out is the software side of things, in combination with the other factors such as hardware/price. Although the Deck ain’t beefy, it’s got enough juice to do a lot at a battery rate that isn’t terribly abysmal, especially for lighter indie titles and emulation.
The other factor here is outside support and adoption. There are tons of options for third party customization, such as skins, buttons, pads, cases, etc. Not saying these don’t exist for the competition, just not at the same scale. Kind of like finding support for a niche android phone versus an iPhone.
