Go Fullscreen (Recommended)
Press F11 to play in fullscreen mode. DeviceRec records at your screen's native resolution, so fullscreen

Make sure "Tab Audio" is enabled to capture game sounds. Enable microphone if you want to add
commentary.

Start Recording & Play
Click "Start Recording" and start playing! DeviceRec captures everything in the tab without affecting
