This is on the PC. My game runs great most of the time: very little lag and smooth. However whenever I'm queued in the group finder I get these strange hitches like the game freezes for a fraction of a second and then goes back to normal. It happens every few seconds over and over again and only stops when I get in a group or quit the group finder.

This is repeatable. It happens always and it's been this way for a week or so.
