Last update made the game unplayable. Anybody else?

Today there has been an update on the client.

I usually have no problems playing this game, works fine on my computer.

But today's update has done something with the client because it takes FOREVER to do anything, play a land, thoughseizem play a creature, it will take from 10 to 30 seconds.

Playing decks that require interaction and sacrifice permanents is an absolute chore, right now I am on a game on turn 5 we barely have done anything and we have been at this for 30 minutes, and I suspect my opponents are having the same problem.
