What is minecraft jvm arguments?

Minecraft JVM arguments are a set of parameters that can be used to customize the way the Minecraft Java Virtual Machine (JVM) behaves. These arguments can be added to the command line or the JVM arguments in the Minecraft launcher to modify the Java Runtime Environment (JRE) settings and make changes to how Minecraft runs.

Many JVM arguments can be used to optimize performance, increase stability, and reduce lag. Some of the most popular ones include -Xmx, which sets the maximum amount of memory that the JVM can use, and -XX:+UseG1GC, which enables the Garbage First (G1) collector, a more efficient garbage collector that can reduce lag spikes.

Other arguments can be used to enable debugging, change CPU and GPU settings, and customize networking settings. For example, -Dminecraft.client.texturepackname can set the default texture pack, and -Dfml.ignorePatchDiscrepancies can be used to ignore patch discrepancies in Forge.

Overall, Minecraft JVM arguments can be a powerful tool for optimizing and customizing the Minecraft experience. It is important to research and test these arguments thoroughly before implementing them, as incorrect usage can cause unexpected issues and crashes.
