A busy weekend ahead perhaps? Steam Play Proton 6.3-5 is out now

By - | Views: 17,308

Valve announced the latest version of the Steam Play Proton compatibility layer is out now with 6.3-5. Don't know what Steam Play and Proton are? Steam Play is a feature in the Linux Steam client allowing you to run compatibility layers like Proton, which enables you to play games supported on Windows. Be sure to check out our dedicated page for the full run-down.  This follows on from the test release that went out earlier in June pulling in many fixes and improvements overall.

For this release these titles should see better video rendering:

  • Bloodstained
  • Deep Rock Galactic
  • Metal Gear Solid V: The Phantom Pain
  • Resident Evil 2 (2019)
  • Resident Evil 3 (2020)
  • Team Sonic Racing

The Windows versions of these titles should now be playable with Proton on Linux:

  • Sid Meier's Civilization VI
  • Crypt Stalker
  • Dark Devotion
  • Dorfromantic
  • Far Cry
  • Hard Reset
  • Hogs of War
  • Might & Magic: Clash of Heroes
  • Pro Cycling Manager 2020
  • Sang Froid - Tales of Werewolves
  • Secret of Mana
  • Trainz Railroad Simulator 2019

There's also improved controller support in the likes of Hades and other Unity titles plus fixes for CyberPunk 2077, Darksburg, Conan Exiles (and other Funcom launchers crashing) and a fix for missing audio in Project Cars 3.

You will also see improved GPU device selection (for those with more than one GPU), an update to the Direct3D 9/10/11 to Vulkan layer DXVK to version 1.9 and also the VKD3D-Proton layer for translating Direct3D 12 to Vulkan had some of the latest work on it pulled in.

See the changelog for more. Updates come through the Steam client like any other game or application, just ensure you have Proton 6.3 installed.

Update - 26/06/21: Proton Experimental also saw an update. It pulled in the updates from 6.3-5, plus it also mentions "support for Nvidia DLSS" and that "Resident Evil Village, Forza Horizon 4, and Anno 1404 - History Edition are playable".

It's good to see Proton going from strength to strength, but I still play mostly native Linux; both as a matter of principle and because there are so many good titles available.
I wonder if Borderlands 3 works with this version.

I've mentioned my sliding scale before, but I'll quickly run through it again.

A game that isn't native and doesn't work in Proton is worth nothing (obviously).

A game that isn't native and accidentally works in Proton is worth maybe 10%. It could stop working at any time.

A game that isn't native but deliberately works in Proton (so the developer tests in Proton and fixes their game if it stops working) is worth something like 50%.

A native game is worth full price.

The games that I buy (or wishlist) all count as Linux sales, so the dev gets feedback that there's a market. The sliding scale incentivises better support from the dev. More tux more bucks.

I'll also add that I've already got more games than I've got time to play, and a relatively long wishlist, so the non-native games also get pretty low priority.

I still can't believe how well optimize CAPCOM made this game, compared to the high dpi mouse bug Re6 had for me, it doesn't even look like it was made by the same company.

Now if they could get rid of their fetish for using Media Foundation components them I would be glad

I'm honestly curious, mostly because of how I often see people claim that's all we need/don't need native ports, are there any devs that have actually done that? As in actually support the game through Proton and bill Linux as officially supported, not them just saying to give it a try or that people got it working.

No Man's Sky is the well-known one: they've had specific things in their changelog about fixing things for the game in Proton.

Every game, if you look at their Steam forum, will have a thread of people asking for Linux support. If a dev responds there you can get an idea about their familiarity and testing regime. Some just wash their hands of the whole thing, but others are more supportive.

Some devs will chime in on Proton's github, or there'll be feedback there from another channel.

Having devs engaged like that, and proactively looking for solutions even if they aren't quite ready to make the step to fully supporting a native build, is still worthwhile, I think. Not full price worthwhile, to me, but significant.

The only mechanism currently for having front page Store support for something running through Proton is to have it whitelisted, which means that Valve's taken over support instead of the dev. Testing in Proton and having a not-entirely-supported-but-tested Linux build available don't show on the Store page. Perhaps we'll get another category if Valve release their rumoured handheld. Unfortunately, the "we just hit the export to Linux button but don't actually test anything at all" does show on the Store page, and those aren't games that people should buy.
I picked up Dorfromantik yesterday and it ran fine with Proton—didn't even have to pick a specific version, it just automatically fired up. Definitely a lovely and stress-relieving game.
As always, amazing update, thankyou everyone who worked on it and thankyou Valve for the continued support.
