The memory has nothing to do with CPU utilization. If nothing on the RAM demands processing at the time, the CPU will not be used by it. Soooooo, what part of the program is demanding CPU cycles while nothing is being done?
I also noticed another common fallacy in this thread. System resources do not represent the amount of RAM being used. You can have 64MB of RAM or 512MB of RAM and with both having the same number of programs open, they will both have the same percentage of resources used.
The resource percentage that Windows monitors is two 64kb chunks of memory. Yep, it's just 128kb of memory being measured. They are set at 64kb apiece because that's the size of data 586 style CPUs like to use. One chunk handles keeping track of what processes are open and running, and the other chunk deals with the GUI, as in what shows up on your screen via how many windows are open.
Increased RAM will give increased performance because the amount of data that can be accessed from it increases and its much faster to access than the hd, but it still only uses 128kb of resources, so no matter how much RAM you buy, you still are limited to how many programs you can run at the same time.
OK, guess time. My theory is that the graphics side of the game is being handled primarily by the CPU instead of the graphics card itself. Before someone puts me in my place as to why I'm wrong and how stupid I am, it is only a guess.
