To this day this is the only mod for any game I’ve installed on the Steam Deck. I followed the directions carefully, including the settings and it worked perfectly.

I also used Cryobytes’s “Golden 40” graphic recommendations but did NOT bother installing his utility and still got great results. IMO, even before the 3.5 SteamOS update it wasn’t necessary and is probably even less needed now but the in game setting are money.
RIP. The value of his utility is up for debate, but the quality of his settings recommendations and hard work on optimizing the deck should not be!
