I've noticed that the game runs significantly slow after I defeated Deathstalker. Specifically, I've been fighting Icetusk, Cobalt Lavaback, and recently Spineglider. The slowdown was most significant when fighting Spineglider, where it felt like I was trying to move my character through molasses. After the fights end, the game speeds up slightly, but still much slower than it should.
I've been playing in the evenings JST (as I currently work in Japan). I've been playing solo, so this isn't a multiplayer connection issue.
I've heard that other people have been facing similar performance issues ever since the latest performance patch if they weren't running high-end computers. My computer is just over a year old at this point, so it's not exactly a low-spec computer, though it isn't a very high-spec one either.
