OptiFine 1.18 is a client-sided modification which enhances the visual elements and optimizes the backend performance of Minecraft for smoother experience. It’s developed by sp614x, he has been working on it for a long time and he’s keen on providing regular updates.
What exactly is OptiFine? Do I really need it?
OptiFine gives a performance edge to the user, forces Minecraft Java Edition to deliver significantly higher frame rates on both Older and higher end PCs.

Also, OptiFine adds plethora of video related options such as Anti-aliasing,
From Minecraft v1.8.8 onward, OptiFine by default comes with support for Shaders (formerly known as GLSL Shaders by Karyonix) . Now you will ask what are shaders? They are basically lighting effects which add more depth to the game making it more realistic. However, to enable these eye candy effects, you must have a decent Graphics Card (GPU). For example; Nvidia GTX 980
