OptiFine for Fabric is a modpack that promises to reimplement the most popular core features of OptiFine within the Fabric environment, leveraging Sodium, Iris, shaders, zoom functionality, and improved performance.
Additional note: The official Fabric community also lists a wide range of OptiFine alternatives and notes that OptiFine itself does not natively support Fabric; common alternative combinations include Sodium for performance optimization and Iris for shader support.
