Valve's popular handheld gaming PC recently passed 14,200 officially rated games, meaning there's never been a better time to own one.
This is just talking about games approved through Valve's verification process. There are a lot of games that work that are "unverified", not to mention the entire history of gaming available through emulation.
Given that compatibility improvements can essentially only be expected from Ryujinx now though, does Ryujinx run as well as Yuzu on the Deck? Ideally I'd like to switch to it entirely unless a viable Yuzu successor emerges, but I've heard that it's not as resource efficient in comparison.
In my opinion it's not "as good" as yuzu, for now. That said it still runs about anything I throw at it, but yuzu did it better with higher frame rates.
It doesn't seem like there's much ongoing work on suyu, which isn't surprising since emulators are difficult to develop. Not many people have the necessary knowledge and are willing to work for free.
So yes, suyu is there for people who need it for it's performance, but it seems likely that Ryunjinx continues to improve while suyu won't change much in terms of performance and compatibility.
It's great for the games that are already running well though, especially on low end hardware like the Steam Deck.
Yuzu is better overall, but Ryujinx works weirdly better for certain games. Like, Mario Wonder runs about 40% better for me on Ryujinx for some reason.
