CodeWeavers and Valve today released the big one many have been waiting for! Proton 5.0 for Steam Play is now live.

Looking to get started with Steam Play on Linux? Have no idea what it is? Be sure to check our previous beginners guide for some tips and explanations. We'll be keeping that up to date with any major changes.

This is a big jump too, with Proton moving from Wine 4.11 to Wine 5.0 bringing thousands of changes and likely increased compatibility once again. According to what's been said in the changelog, at least 207 patches from Proton 4.11 were either integrated directly into Wine upstream or aren't needed now.

Since Proton 5.0 brings in the latest DXVK v1.5.4, it also enables Direct 3D 9 to Vulkan by default now too. FAudio was also updated to 20.02, there's also improved surround sound support for older games and improved Steam client integration makes more games with Denuvo playable (Just Cause 3 now works but no saving, Batman: Arkham Knight, Abzu + more).

Overall, a very exciting update for getting more Windows-only titles playable easily on Linux through the native Steam client. Enabling more people to try out Linux and not lose access to their vast library of games.

Full changelog can be found here.

Note: If Proton 5.0 doesn't appear, you can try reloading Steam. It will also download it when you first load a game with it forced as the version for it.


Update 13/03/20 Proton 5.0-2 is out as a minor release:

  • Fix frequent crash introduced in Proton 5.0-1 related to video and audio playback.
  • Fix Planet Coaster crash on launch.
  • Fix Subnautica graphical issue.

I've been wanting to play Abzu since I first saw it, but not without SteamPlay support. Next time it goes on sale I'm gonna swim with the fishes --- wait, uh, without the concrete shoes, that is.

Once JC 3 is patched so it can be saved, I'll install it on my Linux box and keep playing it. I stopped mid-campaign because I just hated switching over to my Win7 box.

I've gotta say, Proton/SteamPlay has earned Valve my loyalty as a game store.

D9VK doesn't work for me, but DXVK (dx10,dx11) works well, anyone can help?
When I play old dx9 games, games don't lunch.

OS: Linux Mint 19.3

Something revolutionary.. For example, Proton works on Windows. Work in games with anti-cheat systems.
Working with the anti cheat would be great indeed :)
Not even CSGO runs on Proton with VAC.

Awesome progression, but I confirm too, still some work to do... No grappling hook in Batman and no saves in Just Cause 3. Performance wise, they are running like native.

I waiting Civilization V could be played nicely. I must use Wine-Steam (lutris) now. The problem occur, because native version don't support my native (Polish) language.

Quoting: ageresWait, does Batman: Arkham Knight really work now? It didn't earlier, though it ran fine with regular Wine Staging.
Not for me...

Update: It works with PROTON_NO_ESYNC=1



Here with Vsync OFF

Same here. Batman Arkham Knight works ootb. No ESYNC tweak. Performances are quite good.

For Just Cause 3, it's another story.. Instead of not starting at all, it gets stuck on a black screen...

Edit: Just Cause 3 starts to a black screen but the intro and input sounds can be heard.

Edit 2: It was a Steamos-compositor issue. Just Cause running like a champ at ultra on Gnome desktop.

Can you report this compositor issue?

In fact, Nvidia 440.59 just got tagged for and installed on Ubuntu 19.10 and both SteamOS-Compositor issues are gone (Shadow of Mordor Vulkan beta and Just Cause 3 black screen).

Hurray!

For some old (32bit) games you might need the respective Vulkan driver, probably something like mesa-vulkan-drivers:i386.
