Ensure your computer is not running out of total RAM, forcing Windows to use the slow swap file on your hard drive.
The Project Zomboid Steam Workshop is massive. Adding dozens of mods increases the heap memory requirement exponentially. The default runtime environment is simply not tuned to handle heavy mod lists efficiently. The Benefits of Using Zulu OpenJDK for Project Zomboid zulu platform x64 architecture project zomboid

Understanding this technical foundation can dramatically improve your gameplay experience, eliminate performance bottlenecks, and resolve common crashes. This comprehensive guide explores everything you need to know about the Zulu platform, its x64 implementation, and how to optimize it for Project Zomboid.
