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

Posted by , | Views: 36,435

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.

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.

Now I can close Fallout 4 to desktop without crashing...
Instead of crashing, it saves the game progress.

Now, they should enable by default PROTON_FORCE_LARGE_ADDRESS_AWARE for ALL 32 bit games..

Pardon my ignorance, but what does this do?

Also, does this mean d9vk is used automagically when you start a game, or do you still have to specify it as a variable?

Pardon my ignorance, but what does this do?
32-bit applications cannot use more that 2 GB of RAM+VRAM combined, so they crash at high display resolution and high graphics settings, but with that option they can use 4 GB. I'm not sure if I understand this correctly though.

So does anyone have Arkham Knight thinking that it's cracked, when run through Proton? You'll know because you're unable to use the grappling hook, and thus be a little more than screwed. This is apparently an anti-crack measure, but I never saw it whilst running the game through wine steam, so it's a little concerning.

I'm not sure if VRAM is even affected by this.
But normal RAM definitely is. And anything could cause them to crash when exceeding 2GB, not only graphical assets. A few game objects too much, a dungeon that's just a bit too large, all could do the job.

Something revolutionary.. For example, Proton works on Windows. Work in games with anti-cheat systems.
