Yep, same here. Two year old, six core Mac Pro with twin Firepro D500s, but editing a simple one page flyer (with no graphics placed at all, just text boxes!) every object movement, scroll, or item creation gives me a second or two lag with the spinning ball. Never had this issue until the latest update.
Currently updating again today (April 4) and I hope to @#$# it fixes it because it's maddening and a massive workflow killer having to stop every few seconds to wait for Indesign to keep up.
