I play Hitman absolution at ultra settings at 1440 X 900 at my rig that is Core i3 2120 and HD7790. I get 44 avg fps and it runs very fine but when there is some new area being loaded or a new mission starts it stutters for almost 5 seconds and then becomes fine. Why this happens? Because of my ram? Its 2 gb ddr3? Should i upgrade to 4gb ? i use 32 bit Win 7
