Hi Dario,

few questions to see if I can help narrow down the issues, technically an UE (5.5 / 5.6) game for Win64 DX12 Platform should work out of the box on the Steam Deck:

  • what RHI is your game using?
  • which version of Proton the game was running on the Steam Deck?
  • is the game using the SteamWork plugin and using IsSteamRunningOnSteamDeck to do specific actions on the platform?
  • can you reproduce the issue if you tweak and launch a default Third Person template on the Steam Deck following https://dev.epicgames.com/documentation/en\-us/unreal\-engine/steam\-deck\-quick\-start\-in\-unreal\-engine ?
  • can you retrieve the UE log from a Development run of game from the Steam Deck? You should be able to connect to the device using any FPT clients like FileZilla or WinSCP.

Thanks,

Daniele

hi there!

If you have at hand a project that you can share where I can repro the issue I can help debugging it.

I would suggest also to look at the log output of a Development build either connecting Visual Studio or retrieving the remote file log in the project Saved folder!
