2. 💻 Increase RAM Allocation by Editing JSON Files
· Open the 'projectzomboid64.json' file in a text editor (like Notepad or Visual Studio Code) located in your Project Zomboid game files.
· Find the 'XMX' value to check the currently allocated RAM. The default is 3GB (3072), which might be insufficient for multiplayer or mods.
· Adjust the value according to your system's RAM capacity. For 6GB RAM, setting it to 6144 is recommended; for 8GB, set it to 8192. (Note: Exceeding your system's RAM capacity can cause game crashes.)
· Caution: Enter the exact number corresponding to your RAM capacity (e.g., 6144 for 6GB) and do not change any other settings.
· Save the file and restart the game.
