Allocating additional RAM to a specific instance in Prism Launcher is often necessary to maintain performance when playing with mods. Minecraft requires a modest amount of memory, but adding visual overhauls, content expansions, or large texture packs increases those hardware demands. Increasing the memory limit in the launcher settings provides the game engine with the resources needed to load complex assets and maintain stable framerates.
