I have an AMD Radeon HD 7400 M GPU in my laptop, but the Gamebar says my PC doesn't meet the hardware requirements. My guess is that it only recognizes my integrated Intel HD Graphics 3000, which is not supported. I've downloaded the most recent drivers for both of the GPUs, but the recording still doesn't work.
Make sure you have the proper GPU drivers installed for your machine then i do these steps:
Open the Catalyst Control Centre.
Click “Power” and select “Switchable Graphics.”
Choose an application from the list or browse and select an application and assign the appropriate GPU.
