Your system information

  • Steam client version (build number or date): 1763795278
  • Distribution (e.g. Ubuntu): Fedora Workstation 43 RPMFusion
  • Opted into Steam client beta?: No
  • Have you checked for system updates?: Yes
  • Steam Logs: Cannot upload on github will update with a link to gdrive.
  • GPU: AMD

Please describe your issue in as much detail as possible:

DirectX shader compiler takes 100% of the cpu for awhile and then explorer.exe maxes out 1 core CPU usage.
Clicking "close game now" doesn't reap the whole process tree.

The steam client cannot create ANY system runtime diagnostics.

Steps for reproducing this issue:

  1. Launch the game.
  2. Observe process list.
