Guild Wars 2 (1284210)

Compatibility Report

• Name of the game with compatibility issues: Guild Wars 2
• Steam AppID of the game: 1284210

System Information

I've been able to reproduce the problem on two separate systems:

• GPU: RTX 3090
• Driver/LLVM version: Nvidia 525.60.11
• Kernel version: 5.19.0
• Link to full system information report as Gist:
• Proton version: Proton Experimental

• Steam Deck running both the Client- and System-Beta
• Proton version: Proton Experimental

I confirm:

• that I haven't found an existing compatibility report for this game.
  • There is an existing compatibility report, but it's closed
• that I have checked whether there are updates for my system available.

Proton Log with the issue: steam-1284210.log
Proton Log from a few days ago, when the game was working fine: steam-1284210.log

Symptoms

The game doesn't launch anymore. It's shown as running in Steam, but the launcher never appears. This issue has only appeared in the bleeding edge-branch a few days ago, but is now also occuring in the regular Proton Experimental-branch.

The line 00c0:00c4:err:sync:RtlLeaveCriticalSection section 00007FF941E4CA60 is not acquired is repeating in the logs, so I guess that has something to do with it.

Reproduction

1. Launch the game
2. Nothing happens

Start by reproducing the launch failure with Proton Experimental on the reported systems, then compare the current Proton log with the earlier working log linked in the report. Trace the repeated RtlLeaveCriticalSection error and related startup entries; done means Guild Wars 2's launcher appears and the regression is covered by an appropriate verification step.
