@catsnake can just point out that Minecraft is not just a simple block game, it has complex texture entities and at any moment the computer is rendering thousands of things on any decent settings. I can personally attest to this because I used to play on a cheap laptop and now I play on a cheap gaming pc, If I tried to run Minecraft any higher than 16 chunks with bare minimum settings without optifine the game was very laggy and had Constant frame dips, but when I installed optifine I could finally has thing like particles and high render distances. Now that I have a half decent pc I can run 16 chunks and decent graphics without optifine and 32 and amazing graphics with. To conclude not every minecrafter has a $5000 dollar watercooled pc so don’t call them retards.
