You said "I have an i7-920 and 8gb of RAM, but Poser will rarely get more than 50% usage out of it, wasting a lot of hardware power. If anyone knows a way around this please let me know, I'm sure it would help the OP as well."

 

I have a total of 24 cores in my main pc (2 12 core xeons) and Poser 8 and Poser Pro 2010 will run 100% cpu utilization on win7 64. What OS are you running?
