I feel like I'm slowly starting to crawl onto the same boat as everyone else. When I first started playing the game (even with the high-level of congestion) I could run smooth at max settings at 45-60FPS.

Since the Oct 15 update and transferring from a Japan server to an NA server, I would randomly get extreme levels of lag in certain Dungeons(like Cutter's Cry). There would be a 1 to 2 second delay.

I've had to dumb down the graphics to make it more manageable (turned off the all the shadows, lowered grass graphics, blur, ect..). It seems to have helped, but I still occasionally suffer a .5 sec delay in some dungeons (mostly during battles).
