realMyst is a large application and requires a lot of memory to run efficiently.   There are many background processes that run on the iPad that also use up memory which can then impact the performance of realMyst. 

 If you are experiencing lag and frame rate issues, we recommend that you:
 1. Reboot your iPad
 2. Put your iPad in "Airplane Mode" while playing realMyst
     
 If you still encounter lag and frame rate issues after trying these suggestions, please submit a support ticket or email support at support@cyan.com.
