FSR Reloaded
by cdefpigger
FSR Reloaded brings AMD's FidelityFX Super Resolution to Minecraft, so the game can render at a lower resolution and upscale the image for higher frame rates.
What it does
Minecraft renders internally at a lower resolution, and FSR reconstructs the picture at the display resolution. Temporal upscaling reuses detail from earlier frames, which keeps edges cleaner, and the included RCAS sharpening helps blocks, leaves and items stay crisp instead of blurry. Rendering fewer pixels cuts the work the GPU has to do, and the gain is largest at high resolutions such as 1440p and 4K.
The mod pairs well with LOD mods, since upscaling lets a player keep large view distances without the same GPU cost. Its aim is to stay lightweight and work directly with Minecraft's rendering system, so it needs only Fabric API. Cloth Config API and Mod Menu are optional. Most shaders work with it, but the mod's own notes say to expect visual bugs and performance issues with some of them.
The mod runs on the client alone, and it is published for Fabric only, for the game versions 1.21.11, 26.1.2 and 26.2. It is released under the MIT License and is open source, with source code and an issue tracker linked from its listing.

How it compares
Better Resolution is a Fabric client mod for 1.21.1 – 26.3 under All rights reserved, so its license does not allow open reuse. Salt's Anti-Aliasing is an open source MIT Licensed Fabric client mod for 1.21.1 – 26.2, and it smooths edges rather than upscaling the render. RenderScale covers Fabric, Forge and NeoForge for 1.20.1 – 26.3 under the MIT License and is client-side only.
