The Asahi team never fails to impress. You can support the project at their Patreon. You don’t need to care about Apple hardware to see the value in the work they’re doing getting ported over to ARM PCs. Who knows? You might be donating to the health of your preferred distro on a device you will own down the road.
So how does that work given that most Steam games are x86/x64 and the M2 is an ARM processor? Does it emulate an x86 CPU? Isn’t that slow, given that it’s an entirely different architecture, or is there some kind of secret sauce?
You asked how it works, the post states how it works. You also asked if it’s slow, which is clearly answered in the post (though you didn’t quote that part). You also asked if there’s some “secret sauce” allowing it to be fast, which is also a weird question since everything used is listed in the post.
If something wasn’t clear to you, why not specifically ask about it? Even in this comment, you still don’t specify what you don’t understand. What kind of answer are you expecting to get?
Definitely going to incur a performance hit relative to native code, but in principle it could be perfectly good. It’s not like the GPU is running x86 code in the first place. On macOS, Apple provides Rosetta to run x86 Mac apps, and it’s very, very good. Not sure how FEX compares.
No Vulkan and just WineD3D on OpenGL makes it hard to consider good. Might be pretty good after they find a way to run Vulkan on it, which might be tricky given how the hardware was explicitly designed to run just the proprietary Metal API.
I’ve heard something about Apple Silicon GPUs being tile-based and not immediate mode, which means the Vulkan API is different compared to regular PCs. How has this been addressed in the Vulkan driver?
…which is a funny fact because I had another Reddit user swear up and down that TBDR was a big problem and that’s why Apple decided not to support Vulkan and instead is forcing everyone to go Metal.
I’d argue that it may come to that, given the poor availability of (steam) games for the macos platform. And when it is available, you may end up with a disclaimer that it may not run anyway.
If the game relies on 32bit libraries, IIRC macos dropped the support for those? And there’s a lot of games that rely on 32bit.
So if one really cannot play 32bit games on macos then yeah. If the game doesn’t do anything fancy with OpenGL, and is using OpenGL, then I think that it’ll run great.
As an actual M1+Asahi user and a gamer: Asahi is not there yet. Right now, if you’re on macOS, Crossover (or Porting Kit) and/or Parallels is able to run more games and with better performance compared to Asahi (using krun + FEX). Also, Steam on macOS (non-native) is much more peformant compared to Asahi, where it’s currently slow and glitchy.
But that will all change in the future once the Vulkan driver and TSO patches are ready. FEX is also seeing a lot of improvements, so by the end of the year, there’s a good chance that gaming on Asahi would be much better than macOS.
You can use Whisky which is a convenient wrapper for WINE to run the Windows version of Steam. Simple games like Dredge work flawlessly on my M1 but anything used for benchmarking FPS is unacceptably slow. Translation of Intel code is the biggest issue. I assume Asahi has the same limitations as Mac OS but it is impressive what they’ve been able to do.
There’s a native Linux version of Steam (at least for Ubuntu / Mint) that works great. It also uses a proprietary Wine wrapper called Proton, that’s pre-configured for all your Steam Library games.
Sorry I was very unclear. Whisky is an app for MacOS. I’ve used Steam on Ubuntu as well and it works OK but sometimes is a pain to find a version of proton that works for a given game.
Native in this case means processor architecture, not OS. The Linux Steam is still x86/x86_64 code and to run it on an ARM system (even running Linux) will require an emulation layer. Thos adds substantial amounts of overhead, much more than Wine/Proton does for Windows games on Linux.
Asahi means “rising sun” in Japanese, and it is also the name of an apple cultivar. 旭りんご (asahi ringo) is what we know as the McIntosh Apple, the apple variety that gave the Mac its name.
If you’re thinking what I’m thinking, it doesn’t seem to have anything to do with beer.
