About this Mod

I need to rewrite this for V26. And in order to do that I have to learn Vulkan, please give me time :)
Have you ever wanted Anti-Aliasing without shaders? This mod aims to create a light and simple post processing effect do keep the vanilla look.

About This Mod

As of right now, this is just to get the framework out. I will continue to update this to look better (and work better if it ever becomes too heavy) as I learn more about graphics shaders.

The toggle keybind is F9 by default.

PSA - It looks blurry currently. I just have a very very simple FXAA code set up.

Compatibility:

This should be compatible with anything that doesn't change shaders. Should be compatible with Iris as long as you are not using any shaders.
Let me know if there are any compatibility issues you all find. :D

Using this in modpacks or mods

If you decide to use this in a modpack, please give me credit. As I have the code publicly available, you all are allowed to make changes and redistribute it, but you must say that you built off of my code.

Frequently Asked Questions

Simple AA server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.1). You can switch loaders with one click in the panel.

Is Simple AA compatible with fabric?

Simple AA officially supports fabric for Minecraft 1.21.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Simple AA – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Simple AA consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
