Forgive me if this has already been covered somewhere else.
The game uses way too much memory and processor for whatever it's doing. The start screen, the menu with the planet in the background uses 1.75GB memory and runs all four of my cores to 60%. A multi-threaded main menu!
It goes without saying that when I'm actually playing the game proper it's basically eating up every computer resource it can from the jump. Note that it doesn't seem to need the memory or proc time it's gobbling up. (It runs fine whether it's the only app running or one of many.)

Is this (consume all available resources) the expected memory and processor profile of the final version of the game?
