Larian have just released a fresh update for Baldur's Gate 3, which brings a Native Linux version made for the Steam Deck. I mentioned they were doing this in a recent GamingOnLinux article talking about an issue it had and now it's here.
Originally, it used Proton to run the Windows version (like a lot of games) but Larian say with the new Native version it should result in a "more stable framerate, lower loading times, and smoother gameplay".
Additionally, the work they put into this update benefits everyone as they said you should see "overall improvements to the way game models are streamed on all platforms, which should reduce framerate spikes in busy areas, such as the Lower City in Act 3".
For Steam Deck players, you won't lose any saves with the move, as long as your Steam Cloud is up to date. Larian also put up a dedicated guide for the transition to the new version. In short: if you wish to change it over before Valve re-run it through verification to swap it, go into the game Properties -> Compatibility, tick the "Force..." box and select "Steam Linux Runtime". Although, that should already be done by Valve.
As for Desktop Linux support, Larian gave a definitive no on that:
Now that there is a Steam Deck Native build, is Baldur’s Gate 3 supported on Linux?
Larian does not provide support for the Linux platform. The Steam Deck Native build is only supported on Steam Deck.
I'll refrain from moaning about the Steam Deck being treated like it's not Linux. But I get what they're saying, this is specifically for the Steam Deck as a device with SteamOS Linux. For all other Linux systems from PCs to different handhelds, you'll want to stick with Proton.
The issue for Desktop Linux is a bit confusing. Larian has set this for Linux + Steam Deck, so right now the Native Linux version will only download on Steam Deck and leave Desktop Linux with a broken empty download (or broken update if you had it installed already). You will need to manually force Proton until this is solved. I sent a bug report to Valve on it. Update: 20:21 UTC - looks like this has been fixed and it now downloads on Desktop Linux.
All the changes for this update below:
Crashes and PerformanceGameplay
- Fixed a potential crash related to the Slow condition during combat.

- Fixed a bug causing the Apostle of Myrkul to regain Hit Points every time you load a savegame mid-combat in Tactician and Honour Mode.
Cinematics
- Fixed a bug causing the sounds that djinn summons make when they follow you to loop continuously, creating an uncharacteristic metallic thrum.
- When you're on the ground floor of Felogyr's Fireworks, the smokepowder explosions going off on the floor above will no longer sound like they're happening right next to you.
- Fixed the audio levels for a rat in the Lower City that you, tragically, couldn't hear squeak when it squoke.
- Fixed missing SFX when preparing to cast Wind Walk.

Speaking on X, Larian's Swen Vincke said:
Article taken from GamingOnLinux.com."The story of how this came to be really is one of true passion. The Steam Deck native build was initiated by a single engineer who really wanted a smoother version of the game on Steam Deck and so he started working on it after hours. When we tried it out, we were all surprised by how good it felt and so it didn't take much to convince us to put our shoulders behind it and get it released. It's this type of pure passion for their craft that makes me fall in love with my developers over and over again. Considering myself very lucky to have people like him on my team. Try it out!"

So let me get this straight. They ported the game to a whole nother platform, arbitrarily restricted it to a device that benefits very little, and will not be making it available for desktop systems that make up more marketshare, have significantly more users asking for it, would benefit from it far more, and would actually be impactful to the wider industry for having a GOTY winner ported natively to the platform.
Instead, they spent all that time and effort limiting it to one device whose only benefit to a native port will be less battery consumption and marginally faster loading, won't even run at 60 FPS and in all likelyhood doesn't even have the potential to earn a single extra sale.
...that just feels like a waste of development resources. What was the point? Why even bother?
Yeah, nah, I'll just take my chances running the Steam Deck version on my desktop. If it doesn't work at least it's better than the hardly playable lagfest that is Baldur's Gate 3 through Proton, cuz then it's not giving me false hope of having fun.

SteamOS accounts for roughly a third of Linux users on Steam, making it the largest single distribution. The rest is highly fragmented, which is why "it runs here but not there" is such a common story.
But the development is positive. Deck-focused ports can absolutely simplify desktop Linux support. The Deck acts like a "Linux console" with a pinned runtime, which helps developers ship something stable. As standardization advances (Linux Runtime, Container, Wayland, driver) the extra step to support desktop Linux becomes smaller.
If Valve manages to sell the Steam Deck to significantly more people, ports will follow. I think that will be the case with the Steam Deck 2 in a few years.
Well, you CAN technically play it, but it's about as fun as punching yourself in the face over and over again.
