That claim is incorrect. Minecraft already calculates nearby blocks and render distance by default — a resource pack does not suddenly add that system. Most FPS/resource packs only modify textures, particles, animations, or visual effects. In many cases they actually LOWER performance usage by simplifying those assets.

Also, game latency (ping) and rendering performance are different things. A resource pack usually cannot reduce internet ping, but it can improve FPS stability and reduce visual lag/input delay by making the game easier to render. So saying “it increases performance consumption because it calculates distance to blocks” is misleading unless the pack contains heavy shaders, scripts, or dynamic effects.
