Me neither. I only (have to) use Windows at work, all my own PCs have been running Linux for decades…

I do know however, that WSL emulates most (but not all) Linux syscalls, so you can ran (nearly) all Linux programs on Windows - including WINE. There is also a driver in Mesa so that you can render 3D graphics from within WSL on any DX12 graphics card.

They will likely write their own emulator, but don’t forget about WSL. You can already run WINE on Windows, I wouldn’t be surprised if you could also run FEX+WINE on Windows for ARM.

by intercepting syscalls and executing them directly

Not only syscalls. FEX and Box64 also allow using native libraries instead of emulating them. That leaves basically only the game logic to be emulated.

Yep. The big question is if the gap will close enough that ARM chips indeed end up delivering better power efficiency with emulation than an AMD64 chip that delivers the same performance without emulation.

My bets would be on the native AMD64 chip ending up more power efficient. To be honest, I would not bet too much money though.

ARM based Deck would be a huge improvement to battery life. Don’t get your hopes up too high. You will need an emulation layer like FEX of Box64, and unlike WINE those do have quite a substantial overhead.

It is impressive how far those emulators have come, especially since they got the option to use native libraries instead of emulated ones, but the game logic itself will always need emulation…

This doesn’t mean it can’t be done, it just means that the ARM CPU needs to be pretty fast to counter the emulation overhead, and that’s why I have my doubts about the energy efficiency…

(Btw: I have tried running several AMD64 games on my A311D powered MNT Reform laptop with Box64. It’s impressive how well the emulation runs, and how many games are actually playable already. However, I also encountered a lot of games that don’t reach enjoyable FPS on that hardware. With a faster ARM chip though…)

I only use my Steam Deck while I am away from my gaming (Linux-)PC. The reasons for this are that for me a big screen wins compared to the small (and relatively low-res) display of the Steam Deck, and also the games I usually play play way better with mouse and keyboard than with gamepad input… Also, the Steam Deck is relatively heavy, so gaming in bed or stuff like that also isn’t that enjoyable…

That said, the Steam Deck absolutely shines in situations where I cannot access my gaming PC. I usually take it with me when I go for a longer train ride, and also brought it along for vacation.

Compatibility wise I am in the situation that all the games I ever tried are working on the Steam Deck, but that’s mostly because I have been using Linux exclusively for decades, and have made it a habit to check if a game is going to work before buying it. Though, in recent years that habit slightly changed, thanks to the work Valve has put into WINE development. While back when I switched to Linux most Windows games would not run via WINE, nowadays one can expect that almost all games do. It is still a good idea to check protondb first, of course. Also, there are still a few games that need tinkering to get them to run, and protondb usually has some info on how to do that.

One negative point I have to mention is battery runtime. It strongly depends on what one is playing, but very demanding 3D games can drain the battery in 1.5 hours. However, I am talking about the old LCD model here, the newer OLED models run longer with one charge (though I don’t know how long actually).

Another negative is the display resolution. Most games don’t mind running on 1280x800, but some do. This can lead to illegible text, broken UI, or, as is the case with Stellaris, a different UI that is less convenient to use.

And last, but not least, performance. The Steam Deck GPU is just enough for the built-in display’s resolution, and also only under the assumption that games are reasonably optimized. I have not yet been in the situation that I would have gotten unplayable FPS, but I have heard a lot about games only running with 20 FPS, and needing upscaling… So, basically don’t expect it to run Crysis (yes, I know that joke is old, and that the Steam Deck can run Crysis just fine).

No. Or rather, not yet. Valve has not released SteamOS 3 for anything other than the Steam Deck, but is planning to do so at some point in the future.

I honestly wouldn’t recommend SteamOS for anything other than a dedicated gaming device though. It excels at its use case of launching games via Steam, but for everything else it is quite cumbersome… I would much rather install a general purpose Linux distribution and run Steam on it.

I would rather trust GamingOnLinux here:

While it is not in any way officially supported by Valve, they have now released Windows drivers for the newer Steam Deck OLED model.

(emphasis mine)

To answer your question: I use an Xbox Series X gamepad. However I cannot recommend this cheaply built piece of junk.

I also tried to use the DualShock 4, but with that I had the problem that it interfered with my WIFI connection. I’m not sure if this is a general problem, or only happens with my WIFI base station though. Also, the DualShock controller has a severe drawback, and that is its short battery runtime, compared with the issue that you cannot easily switch batteries…

So, my recommendation: An Xbox One gamepad. While I don’t own one, I am using them regularly at work, and they basically have all the advantages of the Xbox Series X gamepads, and have a way better build quality.

I would also recommend Xbox 360 gamepads, but they need a dedicated base station, which is very expensive.

And their gamepads for Xbox were pretty good too. Past tense, because those of the Xbox Series X suck (including the “Elite”).

and adding it to Game Mode

Wait, waaaaaat? Lutris can do that? Okay, time to download it on my Steam Deck, like, right now. (Okay, not actually right now, I am at work, but today in the evening.)

Just to add this: Star Control 2 is not only free (as in free beer), it is free (as in free speech). The open source project is hosted on SourceForge (yes, that still exists), and has a website that is worth checking out: https://sc2.sf.net/

Anything 2D… Or emulators for old (2D) consoles, or DosBOX…

I already asked over at the GoL forums, but I think it’s worth repeating: Does anyone know where one might find a legal download of this game? https://www.mobygames.com/game/3132/rally-championship-international-off-road-racing/

It seems GoG does not have it, and I would really like to play it again - for nostalgia reasons.

You can also use Steam as a launcher. In Desktop Mode there is a menu entry “Add a Non-Steam game to my Steam Library”. For Windows games, you can just browse to their .exe file. After adding it to the library, you can open the Library Entry’s Properties page, and choose Proton as compatibility tool.

That way you get your non-Steam games in your Gaming Mode launcher.

To get nicer images, there’s a website named https://www.steamgriddb.com/ that also has a small Flatpak tool that you can use in Desktop Mode to set icons/banners for your Non-Steam games.

The Orange Pi Neo will ship with a custom version of Manjaro, and is imho the only Steam Deck competitor that is even worth considering.

Just take an Xbox 360 gamepad, and an Xbox Series gamepad in your hands and compare them. Press the buttons, move the sticks, try the triggers.

One feels like quality. The other feels like <beep> - especially the D-Pad.

Stay away from any Xbox Series X/S gamepads. They are cheaply made trash.

I bought the standard version of it for my Deck, expecting it to be somewhat comparable to my Xbox 360 gamepad (which I really like, but which does not have Bluetooth), but nope, it is so much worse…

A friend bought the Elite version, and he also agrees that those gamepads are utter garbage.

When I got my Steam Deck the official dock did not exist yet, so I went for a relatively cheap USB hub with power delivery and display port alt mode. I ended up buying this one, and haven’t regretted it since: https://www.dlink.com/de/de/products/dub-m420-4-in-1-usb-c-hub-with-hdmi-and-power-delivery

I played without mods, and had the same issue.

I’m pretty sure it’s a bug in the native LInux version of Pathfinder: Kingmaker. The Linux build works fine, as long as you play with mouse/keyboard, but with gamepad input the kingdom management screen doesn’t work at all…

What I did in order to play it on the Deck was to tell Steam to use the Windows version via Proton instead. (Properties -> Compatibility -> Force a specific compatibility tool -> Proton (I don’t remember which version I used).
