What stat are you looking at? committed memory? I mentioned that is fairly high for the game, but it's not actually memory that's allocated and in use, it's a sort of pre-allocation where something says "I think i'm going to want to use this, reserve it for me". If you have virtual memory then this will never really impact actual memory usage. Be better if it didn't do it, but it's not really much of an issue in my opinion. More useful is to look at the private working set size and that's what I was referencing in my numbers.
