We will be departing from the Classic Controller Config in Fortuna: The Profit-Taker - Update 24.2.9 as it has for long presented numerous issues and bugs in testing and on launch of new Quests, features, systems, ect. We’re at a point now where Warframe is at a size that this Config introduces surmounting issues that ultimately slows testing.
If you are a Classic Controller Config Tenno and you'd like to prepare for the change before the update goes live, you can change to the New Controller Config and start customizing your controller bindings to your liking by going into Options > Customize Controller. When the update goes live, Tenno using the Classic Controller Config will be defaulted to the New Controller Config, but customizing will always be available if desired!
