Unplayable Lag with Beast Tamer and Large Mob Skills

Do I need to have more RAM to access while playing? That seems like a possibility since I don't exactly have a gaming computer.

its a BT issue; im able to play only when i turn down System> System Options> EFFECTS to minimum;
other lag issue is triple pet + auto loot (Item Pouch Skill).

the second is a more general issue, and counter productive, farming inside EVO. reducing the number of pets, or looting before too many drops appear on the floor, are solutions.
