An interesting thing that turned out to be a gamechanger – a potentially universal stuttering and performance fix for Unity Engine games on Steam Deck.
The addition of three commands in the configuration file significantly improved the performance of the games – at this point Cult of The Lamb, Dinkum, and Tinykin were tested and each received significant performance improvements and heavily reduced stuttering.
All you have to do is turn on Desktop mode and go to the location where the game is installed. This is where we need to search for the config.boot file. In the case of the Tinykin game, it looks like this:
/your installation folder/steamapps/common/Tinykin/Tinykin_Data/config.boot
Edit the “config.boot” file and add the following commands at the very bottom:
Save the file and return to Gaming Mode, then simply launch the game.
The fix should work in many other games – I will always try to inform you about it in passing.
