Ipad Notification Lag. Please Help

Hello guys,
I am using the new ipad for quite some time now and there is one thing that bothers the smooth iOS Experience. Whenever a notification pops up lets say Email, or from any other app, while I am playing games then the frame rate drops for a few seconds. I do not know why this happens or is it a bug only on my device.
Do you also experience the same problem? If no, then how do I fix it.
