Recently had a question about a game running on the deck, and actually got me thinking since steamos settings were briefly discussed: what are the settings to change for a steam deck, or tools to add? I do not mean more fps or more performance per say only, but more battery life or just better tools for certain aspects of the deck.
TDP limits can sometimes give you increased battery life with no change in game quality. However if you ever notice the game freezing or stuttering, make sure to disable TDP limit and see if that fixes it.
