Compatibility Report

  • Name of the game with compatibility issues: Overwatch
  • Steam AppID of the game: 2357570

System Information

PROTON_LOG=1: steam-2357570.log

I confirm:

  • [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 load Overwatch, the RAM usage starts around 4 GB but it slowly climbs, usually reaching around 17 GB during my testing. The RAM usage climbs to about 14 GB when I am sitting in the main menu and has surpassed 18 GB during a game.

I have attempted to use the recommended Proton version and also tested forcing Hotfix, Experimental, 10.0-4, 11.0 (beta), and 9.0-4 with similar results.

Reproduction

Run Overwatch on Kubuntu Linux.
