How to Allocate More RAM to Specific Programs on Windows
RAM, or random access memory, is used to make programs start up faster and perform tasks in a fraction of the time it would take if the program had to be loaded from your hard drive. RAM is vital to the performance of any program that needs to access a huge amount of data.
For example, a word processing program will not rely heavily on RAM due to its low performance requirements. However, a detailed Excel spreadsheet or Photoshop will need as much RAM as you can spare. The same goes for games. In many cases, you should allocate extra RAM to gaming, especially if you use a lot of mods.
This applies to titles like Minecraft, as well as games like Shadow of Mordor, which require a whopping 8.3GB of VRAM. The good news is that you can allocate more RAM to specific apps to improve their performance.
