Zulu Platform x64 Architecture an open-source implementation of the Java Development Kit (JDK) used to run Project Zomboid on 64-bit systems

x64 architecture, also known as AMD64 or x86-64, is a 64-bit version of the x86 instruction set architecture (ISA). It was introduced by AMD in 2003 and has since become a widely adopted standard in the computing industry. The x64 architecture provides a significant increase in address space, allowing for more memory to be addressed and improving overall system performance. The x64 architecture is used in many modern CPUs, including those from AMD and Intel.

This architectural upgrade is a foundational step for the upcoming Build 42. By optimizing the underlying engine now, the developers are preparing for the massive influx of new features, including animals, expanded crafting, and deeper underground basements. zulu platform x64 architecture project zomboid new
