A Hat in Time: How to Fix Modding Support

Here is a guide on how to fix modding support for A Hat in Time running inside Proton on Linux.


You just installed Linux (or bought Steam Deck, like me) and tried to launch the game with mods…
Unfortunately, game only shows the splash screen and crashes right before it suppose to show the UE3 logo…

1. Open Steam and go to the Library tab
2. Open the properties for “A Hat in Time” (right click on the game on the list or click the cog icon)
3. In “General” tab, under the “Launch options” paste this:

PROTON_NO_D3D11=1 PROTON_USE_WINED3D11=1 %command% -noverify

“-noverify” is optional, but it may save you some annoyance
4. In “Compatibility tab” choose the latest Proton version except experimental (in my case Proton 7.0-1)
5. Close the properties window and launch the game!

  1. This got me to reliably launch the game with mods on, but now Hat Kid walks around in circles. Any idea how to fix that?
