Why does GeForce Experience take a long time to check for updates?

GeForce Experience may take a few minutes to download all the settings and screenshots for your games during its first run. Afterwards, it will update itself periodically in the background. Occasionally, our servers will be taken down for maintenance. You can check to see if our servers are offline by visiting our GeForce Forums or our Facebook page. If you experience unusual delays or long download speed, please file a bug using the "Send Feedback" button in the app.
