Hi @kisak-valve, I just uninstalled the game. Might give it a go later but I'm highly confident you can reproduce it using the steps described above. Especially given that raytracing using proton is not (yet) functional.

@kisak-valve this issue is already reported here https://github.com/HansKristian-Work/vkd3d-proton/issues/669

Symptoms

Game reliably crashes when attempting to go down the bunker elevator after meeting Giul.

Reproduction

1. Play "The Caspian" chapter until you meet Giul.
2. Follow Giul to the underground bunker entrance and enter.
3. Start the elevator.
4. Game crashes after a few seconds of being on the moving elevator.

Workaround

Fixed the crash issue by disabling Hairworks.

With new Nvidia drivers 525 game stopped working on Nvidia GPUs. More info: https://github.com/HansKristian-Work/vkd3d-proton/issues/1369

Would you mind trying this change for the B580? : https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/34008

I was able to play the game locally with this.

This seems to have done it. I am now able to advance past the part that was consistently crashing. also the crashing from the main menu seems t be fixed. So far all running stably.

Thanks

Unfortunately, there has been a further crash. This one was in the sams story mission.

Attached is the proton log.

My bad, I botched the change (by changing the approach half way after finding a fix). The MR is updated and it seems to work fine for me.

I pulled in your latest changes and gave it a go. it is still crashing in the same spot again.

Looks like you're running into a GPU hang. What kernel version are you running?

Are you using specific game settings?

I'm using Proton Hotfix on steam.

Sorry, just saw the version up there, should be fine.

I was using proton experimental before. I tried switching to hotfix, and was able to reproduce the crash. this one is not as consistent as the others, but on the third attempt it crashed again. attached will be the proton log as well as a gist for the user.cfg file which should have all of the my settings.

I can also share my save files if that would help.

Really odd... I have no issues playing the beginning of the game (inside the sewers).

The first section played without any gameplay errors. the crashing started in the next section, Moscow. You're able to unlock all of the sections from the chapters menu on the main menu.

There is a part at the beginning of this, where you board the train. that cutscene that plays when you first get on the train is where it would crash consistently for me.

This part does seem fixed for me. I will play that part a few times again to confirm.

The part I am getting a crash in now is in one of the DLC missions, Sam's story.

Playing the Sam's story DLC and it seems to work fine here, no hangs.

The hang happens for me when you are meeting the old captain. you take a boat to find them, it's after the snipe part.

There is a part where you are on the boat and the captain is talking. you follow them get on elevator then after that you go down the hallway. this is where the crash is happening. particularly at the part where it turns right.

The Enhanced Edition using DualSense + SteamInput is broken since at least Proton 8 that I tested back then (it never worked).

It keeps mapping keyboard + mouse on top of the xinput for every gamepad interaction, game icons flash between kb and dualsense icons and every input is duplicated.
We see logs of the game disabling and reenabling xinput for every gamepad interaction (attached).

Game defaults to this server template: workshop://2193678584

Using any other template, including default ones, community ones, will not change the behavior.

All of this is resolved by disabling SteamInput. "Controller Support Info" for this game is wrong since it supports Xbox + DualSense without SteamInput at least (need to confirm further types). Given the wrong controller support information, a DualSense user may be led to enable SteamInput and experience such discussed issue.

The game doesn't support DualSense Edge in any way though (most games fall it back to regular DualSense w/o SteamInput, but not this one), maybe there is a Proton/Wine spoof that can be done to workaround that but it is another topic.
