There is a mod on NexusMods that gives you a lower quality 'low' preset that I found helped me get a more stable performance on my deck.

There is a modded Low ini available on Nexusmods that helps on Steamdeck. Hope that the performance gets better over time though.
What are your specs? I'm interested in trying the DLSS mod but I have a notebook 2080 so not sure how much that will help.
