You always have the option to take a screenshot of your game, even if you don’t have one of these cards.
If your PC can’t record game clips, you’ll get a message like this when you try to make one:
Sorry, this PC doesn't meet the hardware requirements for recording clips.
In that case, do one of the following:
Get the latest driver for your current video card (if your PC has more than one video card, make sure the drivers are up to date for both)
Install one of the video cards listed here
If your PC has multiple video cards and only one supports Game DVR, make sure you’re using the monitor connected to that card when you record your game.
If you have a supported video card whose driver is up to date and you still can’t record games, open Feedback Hub (a Windows 10 app) and add feedback so we can investigate.
