I just reinstalled DMMM for first time since it came out thinking it would run great on my new system, but during the first level at stonehinge or w/e it crawles at aroud 10 FPS in the street areas and even worse when fighting the cyclops. My rig is

-AMD Phenon 9150e Quad Core @ 1.8
-6 GB 6400 RAM
-500 GB HDD
-Vista 64 Home Premium Edition or w/e

I can run most any game on max with 30-60 FPS. I know this game is wierd about systems and such, but I ran it better on my old rig with a 7600 GT and 3 gigs of ram... I installed both patches and they dont seem to help. Any info would be greatly appreciated. Thanks!
