So I have 8GBs of memory on my laptop and in the Minecraft Launcher I have "-Xmx5G" in the JVM Arguements. This lets Minecraft use up to 5GBs and my laptop uses less then 3GB when running absolutely nothing but task manager to see how much memory my laptop uses. But whenever I launch Minecraft, go onto my favorite multiplayer server, and press F3, in the upper right corner, it says that it's allocating below half a GB. Any help?
Minecraft only uses as much as it needs, allocating more won't do a thing to your performance, and may deteriorate it if you allocate more to Minecraft than your computer processes itself.
