RAM usage (especially the usage displayed in Task Manager) isn't typically the greatest metric to use. Is there a reason you're caring about what that metric is? The OS will swap out what's in physical RAM as needed, even if we are sitting on that amount as displayed in Task Manager, some of that could be on disk (and will be should another process need it). If you're running out of physical memory you can look at increasing the page size on your boot drive. This is essentially part of your hard drive you're telling the OS it can use to shunt memory data into if it needs more space. Can help you in the interim. Typically Big Box uses less memory than LaunchBox since LaunchBox stores the local games DB definition in memory and I don't believe Big Box does. This is to make several actions in the app run quicker.
