===== End of Sanitized Report =====
  • Proton version: 9.0-4

I confirm:

steam-218230.log

  • [X ] that I haven't found an existing compatibility report for this game.
  • [ X] that I have checked whether there are updates for my system available.

Symptoms

Whenever I join fights with ~above 30 people the game will eventually start messing up positional information on my client and models will start flying around everywhere. The desync happens faster the larger the fight is.

Reproduction

Launch the game with this hardware/proton version, find a sufficiently large fight, and wait until models start jittering and eventually flying everywhere.

Hello @GleamingPulsar, 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/5295#issuecomment-3008858294.
