With the Legion Go S, we can now directly compare performance between official builds of SteamOS and Windows

Sorry, what's this got to do with Sony?
The only game in the main post photo where Windows beats Linux is Spiderman 2, published by Playstation Publishing, owned by Sony.

the gains come from the reduced overhead that linux has compared to windows
literally the next line
..the games here are being run through proton
I really hate the dismissal of the heavy lifting proton does. Proton is what makes gaming on Linux so great. So many native linux games perform worse on Linux vs their windows counterparts. Then again, I'd expect nothing less from Dave2D
I mean, yeah, but if Proton is doing an absolutely flawless job, then it has 0 performance penalty compared to Windows. All the actual gains still do come from Linux having less overhead. So, both are true, that Proton is killing it and that the gains come from Linux.

Battery Life:
Battery life doubled in some games? Now that is even more impressive than 10-20% performance gain.

Most simply put, it's a layer that allows a computer program expecting windows to run on Linux. It isn't emulating anything, just sorta like translating.
Think of it like a language. Windows speaks English, so a program expects to talk in English. But let's pretend like Linux talks Spanish. Proton translates the English commands to Spanish for Linux to understand and execute, and then Proton converts the responses back to English for the program.
The big thing though about Proton is that it's not an additional translation/emulation layer. It doesn't translate into Spanish for Linux, as that would be slow, it makes Linux talk English.
So in your example, imagine you, the English speaking program, want to catch a taxi in Madrid/Linux but all taxi drivers speak only Spanish. An emulation layer would be "translating", so you would have an additional guy in the taxi that you could talk to that talks to the Spanish driver. Proton is not that, it's an English-speaking taxi driver.

I also find it interesting that the Steam Deck OLED has a smaller battery but gets longer life on the same OS

Windows Was The Problem All Along - Dave2D
We could obviously compare performance between windows and steamOS before on the steam deck, or between windows and Bazzite on other handhelds. But this is the first time we have had official windows and SteamOS builds for the same hardware.
Can it play MH Wilds?

I also wonder how much of it is RADV vs AMDGPU drivers. Wonder what the result would have been if the Deck used the AMDGPU drivers instead. Saying it is just "the magic of Linux" papers over a lot.
I think it doesn't really matter, in the end the question is, do I get a better experience as a consumer on Linux or Windows?

What does proton do?
I only vaguely understand it as "thing that makes game playable on other thing."
(And also I have six versions installed on my steam deck whydoIneedsixofthese?)
Proton is the compatibility layer that valve makes that lets you run games on Linux. Proton uses DXVK a program that converts Direct X API calls (windows only) to Vulkan API calls (runs on anything). DXVK alone gives you huge performance benefits (especially on older DirectX 11 and older games) and you can run it on windows.
Proton gives you a ton of other tools that can make huge performance differences.

wrote last edited by [email protected]If you want something capable of running at an actually steady frame rate I'm not sure any computer can accomplish that without some serious tweaking.
Also if you're wanting to play on deck you might try this guide.

I'm not sure what you're saying. Proton is incredible obviously, but by itself it doesn't make games run better. Using vulkan instead of DirectX could improve performance, but presumably most of the performance gain is from not running windows in the background.

DXVK (which also runs on windows) alone gives you a huge performance benefit. Playing world of warcraft on windows I'll see about a 30% reduction in CPU usage and higher performance.
Proton doesn't just get you to almost matching Windows' performance. Proton easily outperforms windows even on higher end hardware where windows bloat isn't a concern.

Hopefully not a dumb question: If Vulkan runs on anything, assuming their game isn't a Windows (Xbox?) exclusive, why don't more people program their games to use Vulkan instead?

I think the example you're using is closer to emulation.
I'm not an expert by any means, most of my technology experience comes from hardware. But Proton isn't changing the Linux ecosystem, and the programs are still expecting a windows environment when they're run via Proton.
From what I recall, Linux and windows can both do the same stuff, they just have different names or different ways to ask for resources. And Proton receives the request for whatever and converts it to the Linux equivalent.
It's not nearly as bad as it was in the past, now that the graphics APIs are system agnostic.

Ah, I missed that. Thanks for explaining

Yeah its wine/proton and linux together. Wine/Proton efficiently handles translating the Windows programmes API calls into POSIX calls while Linux seems to offer a lower OS overhead so there is more system resource available for the games.
I do think Proton gets a little too much credit. Its wine plus faudio, dxvk and other open source projects combined. Proton is great but it is standing on the shoulders of giants.

I'll add for completeness that vkd3d-proton handles DX12 titles, and of course OGL and Vulkan are supported natively.

That my friend, is entering operating system politics.
But the TLDR is: resistance to change, lack of support, bribery, a combination of all 3, features, and much much more!

It's a bit of both, along with the Linux AMD drivers being superior in many cases to the Windows drivers.

wrote last edited by [email protected]Valve did a lot of work to tune the APU in the steam deck for efficiency. It's custom silicon at the end of the day.
AMD just kinda took one of their existing laptop APUs and threw it into handhelds instead of laptops.

It's becoming more common, but it mostly comes down to available tooling. At this point all three of the big game engines have a Vulkan backend available, but that's a fairly recent development. And if a developer isn't using a game engine, writing their own openGL renderer is easy, and writing a Vulkan renderer is a nightmare.
