Steam Deck - UnrealEngine 5 build issue

[Karfagen]

Hi everyone,

I'm trying to run a game built with Unreal Engine 5 on my Steam Deck. I installed the build using the Steam Devkit Management tool.

I use Visual Studio 2022 and compile .exe locally but, unfortunately, due to some issues, I had to install the Visual C++ Redistributable and add it to Steam as a separate application. Now, I have to launch the game with these parameters:

 STEAM_COMPAT_PATH=/home/deck/.local/share/Steam/steamapps/compatdata/3702034389/ STEAM_COMPAT_DATA_PATH=/home/deck/.local/share/Steam/steamapps/compatdata/3245890886/ %command%

How can I make cook a game so I don't need to use those parameters?
If it is not possible how can I pass the Unreal Engine parameter like -llm to the game.

Just simply appending it to the end doesn't seem to work.


Thanks in advance for your help!
