Grendel, do you just post for the sake of posting? Your irrelevant commentary doesn't help answer any questions.
Syrinx, where are you obtaining the information about the memory usage? From the task manager? Assuming you were using the task manager, the "memory usage" column indicates the total amount of memory used by the process (which includes virtual memory). This doesn't indicate how much phsyical memory the process is actually consuming. If your project was a debug build, it also may consume slighty more memory.
Not sure if this answers your question or not.
