Whenever I try to take a screenshot, I have to press the Xbox button and then navigate over to the menu to take a screenshot. By the time I do this, the thing I wanted to take a picture of is gone. Is there a way to speed this up and map the screenshot capture to a button on the controller like you can on the PS4?
There is no dedicated button for taking screenshots on the Xbox controller but there is a shortcut you can use that is a bit faster than the way you are currently doing it.
Press Xbox Button -> Press Y
This will take a screenshot for you right away and save you navigating menus. This should hopefully allow you to capture what you wanted.
