Well the log file is an incredible 3.4gb in size, I do think we're getting a repeating events. I took about 3011 lines and created a new log:

steamlog-appid_1282590.log

I already updated my gist report, let me know if you need anything else.

Many thanks.

Hey there,

having the same issue on Arch (https://gist.github.com/jannis3005/57e8d1bdd7e75e300b11e47af830b791)

steam-1282590.log

Do you need anything else?

Thanks

Hello everybody,

with the option PROTON_USE_SECCOMP=1 i get the splash screen and load screen, but after that the game crashes.

System:
https://gist.github.com/derjokerx/bb4b630572a13aa02667cc9953a4533a

Steam-log:
steam-1282590.log

Edit: Ok, i don’t know why, but sometimes i come into the menu, game starting or change the settings leads to a crash.

Greetings,

I don't think this is up to date anymore.
It still won't launch, but I'm getting a "Unable to load library steam_api64.dll" instead.

Hello fiws,

please copy the 'steam_api64.dll' file from

Steam/steamapps/common/Train Sim World 2/WindowsNoEditor/TS2Prototype/Binaries/Win64/
to:
Steam/steamapps/compatdata/1282590/pfx/drive_c/windows/system32/

..then should be worked.

Greetings,
joker

Thanks @derjokerx ! I knew about that workaround, but this should still be fixed somewhere no?
Can't expect steam deck users to do that :sweat_smile:

Hello fiws,

Cheers Joker! This is still an issue, your fix works

Nevermind, it works! My OS has a hardened kernel option and switching back to the normal kernel build made it work fine.

Managed to get it working by moving the game to my Linux SSD instead of an HDD (NTFS) and used Proton Experimental. Stable FPS, just a few physic slowdowns here and there but nothing too major.

@Carlgo11 I am getting the opposite behavior that you reported. The game is working with a fresh install on 7.0-1 and crashing with an error about being unable to load library steam_api64.dll on 6.3-8. Did you do any workarounds on 6.3-8 to get it working? I suspect that if you deleted (or moved) your old prefix, you would not get that error with a fresh prefix on 7.0-1. If you wouldn't mind temporarily moving ~/.steam/steam/steamapps/compatdata/1282590 to 1282590.bak to see if a fresh prefix fixes the failure, that would be great. I'm not sure if Train Sim World 2 stores anything important in the prefix, so I wouldn't recommend deleting it completely since you got the game working again :)

@alasky17 I haven't done anything special on pre-7.1 proton. On 7.1 I did remove the game folder in compatdata but it didn't work. Not even after a fresh reinstallation.

I did however add nocase to the drive in /etc/fstab which fixed the problem on proton 7.1 and experimental.

I'm a bit surprised that proton/wine doesn't automatically handle case sensitivity though. Seems like something which would be a common problem as Windows is case insensitive whilst Linux isn't.

Hi, @Carlgo11.

We have logic to handle case sensitivity and to detect and leverage insensitivity when possible. See https://github.com/ValveSoftware/wine/blob/proton_7.0/dlls/ntdll/unix/file.c#L1036 and the following functions.

This most likely means that something in your setup tricks the check into thinking you are running case insensitive filesystem while you are not.

Can you elaborate a bit on what FS you are using for your Steam Library and how it was created? Can you share output of dumpe2fs or a similar tool for you particular FS?
