Got a new 500GB drive and another 2gig of ddr2 (another matched pair), clean install of windows pro 64bit, clean install of poser7... I STILL can't get it to max out the CPU..!?!  totally at my wits end here, I've experimented with almost every setting poser has and have had no luck.  I've updated my bios and all mobo and cpu drivers, I've checked every conceivable thing and it SHOULD max out, it just doesn't.  My memory usage(PF) stays around 500-700mb where it has 4gb to play with, my CPU jumps from 4-100% but balances out at 50%.  My PC has lots of 'free resources' when rendering so why doesn't it use them ON rendering?

This is so frustrating, if anyone has suggestions please feel free, this makes no sense to me.
