Last night I was playing for several hours straight and had no frame-rate issues unless going near very dense villages (which is pretty normal).
Today I log in in my home and as soon as I walk outside I drop 20-30 frames (I'm usually sitting at 60fps consistently).
Unfortunately I don't have much more to offer than this. I was mostly wondering if there was some update that would have caused framerate to drop drastically. It causes things to be very jerky and my client has crashed a couple times.
