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

By - | Views: 21,238

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".

Quoting: CatKillerA 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.
What about a native game that works better in Proton?

What about it? Assuming it's not the fraudulent case, where they sell you a Linux game but don't actually test or support it (which you shouldn't buy), but a standard fully-tested and fully-supported native product (which is worth full price) then your choosing to run it in Proton is no one else's business.

What one needs, as the buyer of a product, is to know that the supplier is going to try their hardest to make sure that the product is fit for purpose, and to have recourse if it isn't. If a dev never tests on the platform you're using they can't do the former, and if they can shrug off complaints because your platform is unsupported you don't get the latter. Which makes their product not worth as much.

FYI: according to recent comments on GTA 5's proton issue, Self Radio now works in Proton Experimental:
* Place MP3's in compatdata/271590/pfx/drive_c/users/steamuser/My Documents/Rockstar Games/GTA V/User Music
* Seems to crash if you put in more than 600mb worth of music

I also believe that buy a "new" game because it works well on proton is nuts. It works today, it's easy anti cheat tomorrow. Eventually though new games become old games. Old games -> no more development cycles. No dev cycles -> no (or close to null) risk of proton breaking.

For AAA games often it's just a matter of waiting like 1 year or so until the project goes support mode. With their obsene day 1 prices, waiting it's not a bad idea anyway.

Yep. By the time a game gets to 90% off, devs are unlikely to still be making breaking changes.
