After setting up remote debugging (SSH), I can deploy the game to SteamDeck directly from the editor, start it, and debug it on my PC. So far, so good. Unfortunately, this only works in SteamDeck desktop mode, and KDE probably runs on X11, which is brutally slow, and the game only achieves a single-digit frame rate. It’s almost unusable, so it doesn’t make much sense.
Does anyone have a solution for how to switch to game mode and still use this workflow?
Yes, that’s right, it’s Wayland, of course. Yes, you may be correct in saying that the game is not recognised as a game. For example, the mouse pointer is still visible, which could be an indication of this. Unfortunately, I am currently unaware of how I could deploy it differently to change this.
