Description:

This mod improves Minecraft launch stability by applying conservative Java memory settings while keeping the G1 garbage collector, reducing large upfront virtual memory reservations that can cause startup failures on systems with limited RAM or small pagefiles. The safer runtime defaults are applied automatically to client and server run profiles, so you can launch and play normally without extra configuration. If you still encounter startup crashes on very constrained machines, increasing your OS paging file size or closing other memory‑heavy applications can further reduce the risk.
