Steam Play's Proton beta has been updated with a performance improvement and fixes

Quoting: TheRiddickMac users are being left out in the cold because MoltenVK development has been slow lately, its missing some critical functions still!

MoltenVK is not owned or developed by Steam/Valve in case people jump to that assumption (some do).

MoltenVK is not owned by Steam/Valve of course, but from what I've seen they do contribute.

The obvious reason why MoltenVK is still missing critical functions is that Metal has a fundamentally more narrow purpose than DX12 and especially Vulkan and also these things take time especially when Apple does not contribute at all.

Somewhere I read that Khronos is developing a subset of Vulkan/DX12/Metal that will be easy for application to change from one API to the other. Since every other platform has Vulkan this looks only useful for that.

Yeah, for whatever reason Apple has decided once again that they don't want to play with others. It's the reason why they stopped updating OpenGL and because of it anyone who plays Elite: Dangerous on a Mac is stuck without the expansions because they use shaders only available in newer OpenGL versions. Stupid thing about that is we could support that on Linux, but they haven't given us a port yet, and it's still one of the games that refuses to work in Wine.

Quoting: slaapliedjeTropico 5 (latest) is native for Linux and doesn't need such things. And if Valve is not currently looking at Mac support for Proton, it just sort of reaffirms what I've always thought. People who have Macs do not game on said Macs. I'll throw out that probably 70% of macs wouldn't even be able to handle most newer games (I know I tried Total War: Attila on my work provided one and I think it may have gotten one frame every 10 seconds...) and that makes it a niche of a niche. It's like people who game under Linux with VR hardware :P

It's worse than that. Apple isn't just a non-gaming platform, Apple is refusing open API's and forcing developers to use an Apple standard maintaining their walled garden(METAL). Valve meanwhile is dependent on open standards to make this initiative work. SteamPlay+Proton requires especially Vulkan and even opengl(despite it's name, opengl is not as cross-platfrom friendly as people think where Vulkan was designed specifically for that). It cannot be done any other way.

Apple has their fiefdom, and that's the end of it, and everything that comes with that is why Apple has never broken 10% of the over-all userbase of Microsoft. Microsoft wants to do the same thing but paradoxically is so big that it can't do so easily and is far more vulnerable to having their plans scuttled. What Valve has just done is to break down the wall Microsoft had around Windows gaming, leaving only the Xbox for Microsoft to dominate.

Im astonished. 90% of my one hundred Windows only inventory's games (of four hundred games) works on Linux, thanks to Proton.

I've had less success. No Man's Sky almost wanted to work, got black screen with music. Marvel vs. Capcom: Infinite just did absolutely nothing.

I haven't played much though. Wish I could get SteamVR to work again...

Finally! I got Divinity Original Sin 2 Definitive Edition working. I had backed the game on Kickstarter, because I really thought they'd provide a Linux version. Turned out to be naive.. :-D
It doesn't matter anymore! The game seems to run perfectly now!

Nice, my brother and I were playing the first one cooperatively and still haven't completed it...

I still can't get a single game to work. I've tried the Doom demo, the Castlevania Lords of Shadow 2 demo, and Space Lords. The first two just crash and Space Lords just displays a black screen. I'm not sure where one goes to get help on these things.

The forum here is a good place to start, your pc details will help, OS version, graphics card, video drivers version, which version of Proton you're using (3.7-5 Beta works better for most).

ps I don't own Doom & I can't get the demo to work either, I get the gameoverlay.so can't be loaded Elf class error when I try to run it.

pps ignore my previous ps, that's not the problem, the problem with the Doom demo is Denuvo, why they stuck that in the demo is beyond me.

Funny thing is, I think they removed denuvo from the actual game. I bet they just didn't update the demo... but why is it there in the first place?

This is absolutely awesome! So, the way I understand it - when we install games that use the Proton functionality, there's a report available for the developer to see that Linux gamers are actually out here. If that leads to more games being assured to work with Linux, then that's a win IMHO.

Another thing I was thinking about.. we need to get Valve to somehow let us bring in other win-based games to our Steam library to try with Proton.


Does anyone have a good suggestion for how to get a list of AAA titles that are working good with Proton? I'm looking to get my hands on some good games.

Thanks!
