Simple AA
by ItsGromit
Simple AA is a lightweight Fabric client mod that applies FXAA anti-aliasing to the game without requiring shaders.
What it does
Simple AA adds an FXAA post-processing pass that softens jagged edges while aiming to keep the vanilla look. It works without a shader pack, so a player who never installs shaders can still use it. The author describes the effect as currently looking somewhat blurry and says the code is a simple FXAA setup that may be updated later.
Sodium is required, so it must be installed alongside Simple AA on Fabric. Simple AA is client-side only, so servers run without it and players join without installing anything. Its files target 1.21.1 only, with the 0.4-beta build published on 2025-12-14 on the beta channel. The code is released under the MIT License and is open source, and the source code is public.
The author notes that the mod is compatible with Iris and does not change shaders, so players who use shader packs can keep running it. Compatibility issues are invited through the author's channels. The author also mentions that the mod is meant for simple use alongside other mods and modpacks.
