OptiFine HD (26.3, 1.20.1) – Run Faster, FPS Boost, Shaders Support

OptiFine HD is a mod that helps you to adjust Minecraft effectively. It makes Minecraft run more smoothly and use less resources. Besides, it enables you to run resource (texture) pack HD without installing more other mods. Usually it can double or triple your FPS. Although it was originally designed to optimize game performance and enable the installation of higher resolution textures, it has become an essential tool for installing shaders. In addition to a series of pre-established optimizations, this tool allows us to disable certain graphical options that cannot be turned off without it. This helps reduce graphic elements that consume more resources. One interesting feature of this tool is that its benefits are noticeable whether you have a low-end, mid-range, or high-end computer.
