So I have been having this issue with my chunks loading for about 2 months, I do not know if it is my computer, Minecraft itself or Optifine, usually my MInecraft runs very fast for the reason that chunks load very badly, chunks i have passed by soon fade away and it gets annoying because I am a big PvPer and I can barley see people coming from far away, here are some screenshots, please help!
