i just wanted to report good stuff here, the past 2 weeks and up untill today (7-7-2014) fighting in groups of more then 5 - 7 enemies was unplayable and i had as low as 1 fps most of the time.
but as of todays maint. and small patch i now am getting definate increase of 15 - 23 fps during "most" fights and with alot more enemies onscreen like 20 or more i definately do go down to 4 or 6 fps but, its atleast playable and much much better
