If you have the latest version of Proton Experimental, Valve just recently put up a new Steam Client Beta (October 28) too which allows playing Windows games on Linux that make use of their older CEG DRM. This is quite a big one actually, as it was a total showstopper for numerous games. Valve developer Pierre-Loup Griffais said on Twitter it's only "initial" support and to post any you test on the official GitHub bug report for it.

Some of the titles that may now work include:

  • Aliens vs. Predator (2010)
  • Bioshock Infinite
  • Call of Duty: Black Ops
  • Call of Duty: Modern Warfare 2
  • Hitman: Absolution
  • Just Cause 2
  • Lara Croft & the Guardian of Light
  • Mafia II
  • Saints Row: The Third
  • Sid Meier's Civilization V
  • Sniper Elite V2
  • The Typing of The Dead: Overkill

Plenty more have CEG DRM, so it will take time for all of them to be tested and reported on. Some titles probably still won't work with other issues present but it's getting another step closer. At least those that actually load up in some way now can see additional testing and work with Proton.

A new black Steam client service window will pop up when Steam goes to sort the CEG, eventually that should be hidden from users - so for now it's normal.

Giving a few titles a run myself this morning I was able to test that Saints Row: The Third, Call of Duty: Black Ops and Call of Duty: Modern Warfare 2 seem to work well now.

Quoting: dubigrasuWhatever the today status, those porters, VP/Aspyr/Feral/etc deserve our (at least mine) gratitude, they kept the Linux gaming going as best as they could.

Absolutely. I purchased everything Feral pushed out out of sheer principle.

But surely we must agree that we are happy those days are behind us.

I'm not sure we must. I only buy games that are officially supported on Linux, and until we see more first-party Linux releases of bigger budget games, I can't really be too happy about porters giving up on our platform. But let's hope that Proton actually works as a stepping stone and actual supported Linux releases will follow, like the more optimistic among us like to predict.

I'm not too bothered though. I've always got my wishlist bursting with excellent indie releases so I'll be fine either way.

Quoting: chelobakaAll above titles work with Proton Experimental bleeding-edge beta.
That is interesting, can confirm that GRID 2 works with bleeding-edge beta, but not the normal Experimental.

Any idea what git branch bleeding-edge corresponds to?

I may now open a can of worms but my question is genuine: Why?

Quoting: GuestAppreciation? Valve are doing this for Valve, to lock more into Steam, and build their own little walled garden.

Yes, Steam is the same on Linux as it is on Windows. Anything else would be weird.

But if we for once allow ourselves to talk from a pure gamer perspective and leave politics aside for just a brief moment, Valves efforts to add Linux to their platform - regardless of their economical or strategical incentives - opens up a world of effortless gaming we would simply not have without Steam. And I personally believe there's not a hint of probability that the Linux support would have improved from where we left before Proton were introduced. It was already declining at that point, and Valve saw that only too well. And Steam Deck would never have happened without Proton.

I really see no rational logic why Valve should favour one or the other - like you say, their focus is to recruit and keep gamers on their platform. If that means improving support for Windows games on Linux, then so be it. It'd be easier for *them* if devs ported their games instead. But they didn't.

Because I think it matters. I often vote with my wallet.

Besides, even with that self-imposed "limitation", I can barely keep my wishlist below a couple of hundred titles at any given time.

I can respect that! I did the same, before Proton. Man I have so many barely played indies in my library from that period. :D

If smaller indie games is your thing then strictly speaking you hardly need Steam Play at all? That's my impression.

Here's a snippet of my wishlist:



So yeah... Thank Gabe for Proton. :)

No, I don't need Steam Play. I wouldn't say smaller indies are "my thing" though. I will buy bigger budget games if they interest me and if they support my platform, just like I've done in the past.

Quoting: GuestAll these things happened without Valve, it's just they were hurried along a bit by additional funding.
Absolutely! And this is also very much in the spirit of Linux, to build upon others work. And I fully applaud their choice of using existing technology instead of running a parallel run. Imho they've done everything right.

But let's be honest here: Gaming on Wine was and is quite the hassle and requires a good understanding of how Wine works - and even an understanding of the windows libraries. Not to mention the patience to configure and tweak a bottle for that game. You're bloody lucky if it "just works".

I consider myself to be fairly proficient on Linux, but of the few attempts I did I never got anything I wanted to play to run via Wine. And they all had top ratings on the Wine homepage. I was lucky if I got the installer running... :D It really is a tinkerers project, gaming on Wine.

So even if one *could* run the Steam client on Linux and tinker around to get stuff running it most definitely was not something most did - we dual booted into Windows instead, or had a console at hand.

I do notice you don't want to make light of Valves contribution, but even so: The contrasting reality before/after Steam on Linux is so, so dramatic that we really are talking about one major milestone for gaming on Linux.

I end up functionally with a bias towards "indies" just because I tend to like strategy games and there's no such thing as an AAA strategy game. If there were I'd probably buy it--I buy Civ games and Paradox games, which is as high end as strategy gets; it's just lucky for me that's not quite high end enough to ignore Linux. Makes it pretty easy for me to stick mostly to native titles.
I did eventually give in and buy Galactic Civilizations III. So far I can't get it to run under Proton, but it's been a while since I tried, maybe I should give it another shot.
