Compatibility Report

  • Name of the game with compatibility issues: Dungeon Siege
  • Steam AppID of the game: 39190

System Information

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

There is a glitch where two handed weapons are rendered on the ground at the character's feet instead of in the character's hands. (See the attached screenshot.) This was fixed in Proton 5.13, but has seemingly regressed and is now present again in Experimental. Using Proton 5.13 resolved this issue but renders alt-tabbing in and out of the game to be unstable.

Reproduction

Begin a new game and pick up a nearby 2 handed weapon. (any of the farm tools in the starting area will suffice.) The weapon will render on the ground and point in the direction the character is facing instead of in the character's hands.

Hello @Xeknos, there's several years of changes between Proton 5.13 and the current build of Proton Experimental. Can you find the newest behaving version and the oldest regressed version from the set of easily accessible Proton versions?

Hi @kisak-valve, many thanks for the response. This appears to still be rendering correctly in Proton 9.0-4, but has stopped rendering correctly by 10.0-3.
