Glad to hear you're happy with your purchase!
DisplayFusion relies on Windows' built-in methods for determining when to launch the screen saver, so there's not much we can do there. However, you can assign a key combination to the Enable/Disable Screen Saver functions on the Settings > Functions tab, to make it easier to more quickly toggle the screen saver on/off when you want to play games.
Hope that helps!
Yes, thank you.
I can just disable and enable it while playing games with a controller.
No problem Seth, glad to hear it!
