Personally, I would tend to think that the amount of memory is also the problem. or also your veirtual memory settings. The processor is beefy enough for poser to be sure but the 512 ram is not helpful. I have a system with 512 and it gets boggy with 512. But the other systen with a GB runs far better. But you do have a point and the mil dragon as obj heavy as it is will be a prob on it;s own.
