e-Sword was never designed for a user to have an unlimited number of resources.
Now, you have never said a truer word in your life, and have hit the proverbial name on the head.
e-Sword, as with any computer software has limited capability and capacity to run effectively and efficiently, and are totally dependent on hardware performance capabilities. And the two main pieces of hardware your computer uses to do the work it needs to do are:
- The amount of RAM (Random Access Memory). Includes both the main RAM and Graphics Card RAM
- The Speed of the CPU (Central Processing Unit).
Your computer has been set for the total amount of RAM it can take without Flashing the BIOS (Basic In/Out System). If you have the latest machine, your computer maximum capacity for RAM in the BIOS setting (if came with e.g., 4GB) may be 10 or 12GB. That is the total amount of RAM you can upgrade to without flashing (updating) the BIOS.
Then you have to consider the amount of RAM your Operating System uses. Windows (irrespective of the version) is RAM hungry, and will gobble up about 70 or 80% of your total RAM. And when you put that into perspective, it doesn't leave you that much Memory to play with. Moreover, when you load up an Application (a program), it uses more of your RAM. If you have a lot of files or a huge file for the Application to load, then even more RAM is going to be required.
But, that is not the end of it, you now have the CPU coming into play, because it there you have the "brain" of your system. It is that which processes all the data, programs, and information you put in your computer. Your Operating System also uses the CPU to process the data it needs to send to it, and Windows can and does use about 80 to 90% of the CPU's resources.
Putting all this together and summarizing it with what Josh said, "e-Sword was never designed for a user to have an unlimited number of resources," you can also add, neither is your computer designed to have an unlimited number of resources
, especially if you want it to run both effectively and efficiently, and without crashing (locking up and freezing).
