Proton 5.0 for Steam Play released - it's a huge update (updated)

By - | Views: 50,884

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.

Quoting: BladeforceCan you use this without steam? Not a fan of steam and thinking if steam goes the way of the dodo then linux loses big time

"Proton" is essentially Wine with a few extra patches bolted on, and bundled with DXVK. All of it open source. So yes, it can be used without Steam, assuming the game itself has no dependency on Steam.

Personally I find vanilla Wine + DXVK runs better for me anyway, but many of the fixes going into new "Proton" releases are probably already in the version of Wine I'm using.

Quoting: Wernerreally great that Just Cause 3 finally runs over proton, but sad that it doesn't save any progress, so on every start you have to start from the beginning again :(

just noticed that as well.i was like wait i know i got to a save point.i hope they fix that because it is gonna be quite the pain to play it without saving anywhere lol.

I have trouble with installing Proton 5. Proton 5 isn't visible in my flatpaked Steam installation. I go to library, select tools and only older Proton is present.

Just go into Steam Play in Settings - choose "Proton 5.0-1" from the drop down. It looks like the latest client doesn't have the concept of installing "tools" any more. You can still choose tools from your library, but I can't see a way to install them now.

Edit: Steam will restart when you do this and next game you launch will start the download of Proton 5 in your download manager.

Well, Mafia now runs. This wasn't working with Proton 4 for me, although I notice a few folk appear to have gotten it to work. I've only created a profile so far, haven't started the game proper, but the intro and rendered opening room work fine. Looking forward to giving this a go!

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
GPU: RX480
Driver: Mesa from Padoka Stable PPA

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.
