There is still a memory leak in this game. It’s not as bad as it once was but when I play for more than 3 hrs with +18 hearthlings you will see a slower pace of game (I play on max speed) and continue to get slower until you save and restart the launcher. After that its like I just started playing a new game.
I run this on Win 7 Ult 64 bit
Intel i5-3570k @ 3.40GHz
8gig DDR3 Ram @ 1866MHz
Nvidia GeForce GTX 770
Driver version 364.72
