Framerate Spike and heavy Resource usage

I am experinecing serious framerate spikes while playing that become more severe the longer i play. I typically experience framerate in the low 100's dropping down to single digits every couple of minutes when i initially login becomming more frequent the longer i play. The drop most often occurs when in close proximity to a large group of players. Which obviously occurs quite often. I have found several ways to optimze that have helped overall quality. My hard drive. Ram and cpu take turns maxing at 100% but my video card resources are fine. I have a quad core i5 processor, 8 gig ram. I play the original Insurgency with no ptoblems at all. Any thoughts about what could be causing such heavy resourse usage?
