Tried closing all other programs and restarting the computer. I'm reporting 12+ GB of free memory. I'm not sure what could have happened to cause this and unfortunately I am away from my home network so I don't have a Time Machine backup. Any ideas on troubleshooting this? Only other thought I have is if the performance could be related to network connectivity? If there is a bad wifi connection could it be causing the jittering?
