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. Just started the chapter where you break into the boat, and it goes down to 10-15 FPS, just crazy. My rig is

-AMD Phenon 9150e Quad Core @ 1.8
-6 GB 6400 RAM
-500 GB HDD with 350 gigs free
-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. I didnt install DX 9.0c during the install...I wonder if thats the problem. I have the latest drivers of all my devices also.
