I tried those demos on Epic Store client via Lutris and I solved the audio issues of Beyond two souls installing xact_x64

Apparently the patches floating around for Detroit need help from the kernel because both it and RDR2 have hardcoded Windows system calls that don't go through Windows itself, and so don't go through Wine. Nasty.

Windows and Linux use the same mechanism and the same numbers, but each number does a different thing in each case (even different versions of Windows have the numbers representing different things, so the game developers use a look-up table for the version of Windows, because of course they do 🙄)

So the patch to the kernel is to allow it to see that system calls are coming from a Windows application (based on memory location) and pass them to Wine for interpretation, rather than using them directly and having them fail because the application is sending NtProtectVirtualMemory and Linux is seeing chdir.

What a mess.

The new shader caching with the updated Steam seems to have helped with the stuttering in Beyond: Two Souls. The demo was interesting. If Quantic Dream haven't messed up the full game so much that it doesn't work in Proton I'll probably get it. The messed up stuff that they did with Detroit: Become Human means that I probably won't buy that.

Edit: although I did have to kill the explorer.exe process at the end after I quit.

Excellent. :)

I hope to finally get around to trying it myself soon so I can post my impressions as well.

Quoting: The_Aquabatworks with AMD Mesa driver 20.1 also with AMDVLK drivers, it's an Nvidia issue.

The developers being reckless is not an Nvidia issue.

I'm pleased that you're getting good performance, but that's not why I'm avoiding getting it.

Detroit: Become Human works fine on my system as well (i7-7700k, Nvidia GTX 1070, 440.66.15 drivers - the developer branch), the performance is great. DualShock 4 works with the game.

I used the 5.0-8 RC version of Proton.

The are only 3 problems.

1. After I exit the game, for some reason I can't boot it again until some time passes.

2. The game had horrible audio glitches when running with pulseeffects on (no problems with it off), but adding PULSE_LATENCY_MSEC=90 %command% to launch options fixed it.

3. For some reason the game doesn't boot for me with mangohud turned on.
