Valve and their partners CodeWeavers have upgraded Proton Experimental, the special testing version of Proton where the latest special updates come in with some big stuff.

This is a totally separate version to the normal Proton releases, which you can select for specific games just like you would normally. Right click -> Properties -> Compatibility and select Proton Experimental from the drop-down box.

With the April 22 update to Proton Experimental, here's what's been added:

  • Updated VKD3D-Proton to version 2.3
  • Forza Horizon 4 is playable (requires AMD GPU with latest mesa-git drivers (known good mesa-git commit: `899dd8e60a5228c4506400d621ef6b5abfe5e32c`)).
  • Mount & Blade II: Bannerlord is playable.
  • The Origin Overlay is functional, which allows It Takes Two to be played with friends.
  • Better support Anno 1404 - History Edition.

Update: another small update was added to Proton Experimental hours after this article to include:

  • Fix Red Dead Redemption 2 "Not Purchased" error.
  • Fix Age of Empires II: Definitive Edition hang on startup.

See the full changelog for all the details.

Testing it out myself this morning with Titanfall 2, it definitely seems like the Origin Overlay does now work. Although it seems to dislike the MangoHud overlay and would not work if that was running with the game. There are a few quirks to it in my testing for example: for me opening the Friends List will minimize the game, then when you bring it back the Friends List is there - slightly odd but it works well enough to use.

Great progress as usual.

Quoting: LoftyBut wait, you need this 'exacting' 41+ char number string and sometimes we will even add a 'dash' then a point and a few numbers on the end (oh and also need the right kernal btw.)
I seldomly use git versions, but I think that means that at that commit, (a commit is a code upload, meaning that someone sent code with that hash)...at that commit, the driver looks fine.
this is useful info, for people using the development tree of the driver to switch to that point in time where that commit was uploaded and to have a semi decent experience out of the driver.
As the usual caveat say, "don't try git versions be warned it may eat your hamster" :P , (that's why I say "semi decent" your millage may vary sometimes git versions run games better than the stable ones)

Thank you for a respectable answer


note to self, gits eat hamsters...

Quoting: The_Aquabatdidn't pay attention to the frame rates but seems playable for me. Ryzen 2600+ 5600XT 6GB.

btw what Mesa version are u running with Dirt 5?

EDIT: Just checked and I get steady 60fps.

Man, I tried it again, running smooth, 60fps on high! Those guys are awesome!

Quoting: leillo1975It don't work for me (GRID.... it shows me a "send-bug" window when I try to play it..... This game worked on past. I think they should be a little more concerned about not messing up some games to make others work. I spent my money on that game and now I can't enjoy it.

That's why it's handy to be able to switch between multiple Proton versions. It would be handy if they had a "community recommended" Proton version, and allowed voting (sort of like the Steam Controller profiles).


This game worked on the past because it used DX11, after some updates they cut off the DX11 version, now it runs only DX12, that's why it stopped to work until now.

The problem with proton is that even using the Runtime - Soldier it can work in some cases and not in another, even with similar configurations. Like I said before, this game is now working smoothly.

Sorry, but I played this game in dx12 mode some months ago with vkd3d, and it works. Some versions before the game gets stucked while loading before the main menu. Now simply don't run and only shows the crash report sender. Take a look, i'm not the only one

This is sad, I never managed to work the DX12 version, and as looks like you have a very different hardware/distro (if your GoL profile is updated), this makes things harder. Maybe you should try a newer kernel?

Ah, so that's not really a Proton problem, but rather that the game itself changed. It's the game developers that removed / broke support for users without DX12. No less frustrating for you, but hardly a reason to complain about Proton development.

SOLD.
I'm almost there with you, except I'll wait for a released version of mesa to trickle to my computer in my normal upgrade routines. I messed with mesa-git for Cyberpunk 2077 'cause I was so excited. And I did get it all to work. But I'm not gonna go through all that again every time.
