Do you experience heavy slowdown in tactical combat?

I have been getting heavy slowdowns in tactical combat ever since I got into the Beta.  Whenever I play for long periods of time, eventually a tactical combat will slow down to be unplayable.  Once it happens once, it will keep happening very often, so I just end the combat, restart and restore.

Well I just found out that if you zoom in as close as you can, the slowdown disappears, so you can win the battle, save, and then restore from that... because restoring from an auto-save does not quite work.
