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.
Ext4 can be converted to BTRFS without data loss. The only downside is that you lose ext4’s capability to have case insensitive folders.
