Hello @Patola, err:combase:RoGetActivationFactory Failed to find library for L"Windows.Graphics.Holographic.HolographicSpace" looks like a line of interest followed by an access violation (c0000005) in your log.
Hi, I added the interface for HolographicSpace and implemented some functions that should make the game work. Can you please test it again? I'm not sure if my commits were pulled into Proton, but they were merged in Wine: https://source.winehq.org/git/wine.git/commitdiff/18453129be33fd50d3050dec722df054a181017a
That's amazing to know! I will prepare a proton build with your patch, test the games and get back to you. Thanks!
Trying to merge your wine changes to proton, but currently having issues because it seemingly needs a newer version of mingw-headers which has ivectorchangedeventargs.h. Still trying
Yeah, I don't think I will be able to compile the current proton with your patch, @mohamadaljaf. You modify an already existing code from idl that is in wine 8.6 but not wine-proton 7.0. And there is some change in types between these two versions, and then when I try to change this there is a cascade of other issues. I guess I will have to wait for Valve to resynch their proton fork... As of now I can't see any 8.x branch.
I see, thanks for letting me know, that's unfortunate. Are there any custom builds of proton that are based on Wine 8.x? If not, I guess the only thing left to do is wait for Proton 8.0 to come out.
Not that I know of. Even Proton-GE hasn't gone 8.x yet and Proton-TKG is no more.
We just have the first proton build using wine 8... https://github.com/ValveSoftware/Proton/tree/proton-8.0-1c
Will try with that
Unsuccessful, tried a lot but I've got limited time for this and my life, work, etc...
The new Proton-GE is out, even GloriousEggroll did not base it on the newest wine but Proton 8.0-1c, which doesn't have the new UWP libraries for the game to run.
But nevertheless even if I was successful, now SteamVR is completely broken on my arch linux and doesn't even turn on the headset (on windows it works fine). So I can't really test any build right now.
So we're on Proton 9 now but there is still another game (Pirates VR: Jolly Roger) affected by that? I don't understand, it should have been part of proton already, no? It's two years later!
I've tried running Desperate: Vladivostok again with the latest proton 9 and it still shows that Unreal Engine screen.
@mohamadaljaf since you added the library, do you know what might be happening?
Could you attach the Proton 9 log?
Sure, here you go.
@kisak-valve any chance of using Proton 10.0 to try and add complete holographicscape support?
@mohamadaljaf used your patch given in #8457 to re-test this one too and got the same kind of unreal engine error dialog. Pasting the proton log here if that would be useful to you.
Note: running with SteamVR via Steam Link
This bug was fixed by @mohamadaljaf with his three patches to the proton_10.0 branch. I have created a proton build to run these games while it is not integrated in mainline proton. This is the build: https://github.com/Patola/wine/releases/tag/protola-10.0
The fix came from #8457
