Hello @Anaerobic-ai, we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to https://github.com/ValveSoftware/Proton/issues/3898#issuecomment-3259847794.
Thanks @kisak-valve It's my first Bug Report and I hope I did everything else correct and understandable😅
You guys are great ✌️😁
Compatibility Report
System Information
I confirm:
Steam-Log: https://gist.github.com/Anaerobic-ai/c3b997fcddf7e512a8be538e80cd289f
Symptoms
Hard crashes in specific locations on multiple maps.
Deadfall Compound (Mammon's Gulch map) – approaching or aiming causes immediate crash.
Port Reeka Bridge (Bayou map) – crossing the small bridge to Alice Farm south (~20m) triggers crash.
Ash Creek pond north of the main house (De Salle map) – entering or aiming at the pond (~20x50–70m) triggers crash.
Crashes are 100% reproducible for at least 6 months.
Crashes are hard: task switching or desktop environment may become unresponsive; a full reboot is most off the time required.
Reproduction
Start the game with Proton (tested with Proton 10-GE and Bleeding Edge Experimental).
Go to any of the crash locations listed above. Deadfall is the worst case because you can spawn in Deadfall
Approach or aim at the area.
The game crashes immediately.
Issue occurs regardless of kernel version or Proton version.
Seems related to certain objects or visuals in the world, I would assume
Locations previously worked before about 11 months ago when the "new Map" Mammon's Gulch launched. They updated the Cryengine, and it worked initially. After the first Update since now, after multiple updates of the game, Deadfall never worked anymore.
