Here is how to migrate from the default Java to the Zulu x64 Platform.
The undead will eventually eat your brains, but your computer should not give up first due to a memory leak. The Zulu Platform x64 Architecture is not a magic FPS booster for low-end PCs, but it is the definitive stability patch for mid-to-high-end rigs running modded Project Zomboid.

Add these JVM flags for Zulu x64:
-XX:G1HeapRegionSize=16M \
-XX:InitiatingHeapOccupancyPercent=30 \
-XX:G1ReservePercent=15 \
-XX:+UseStringDeduplication
These reduce memory fragmentation and improve mod asset caching. Add these JVM flags for Zulu x64: -XX:G1HeapRegionSize=16M
