Iris Shaders is an open-source mod for loading shaders into Minecraft. It works smoothly with all existing shader mods & OptiFine shader packs. Sodium is also included with it by default. It’s a performance optimization mod built to counteract the performance/FPS loss when running demanding shaders. Paired together these mods enhance both visuals and FPS in Minecraft better than OptiFine.

It is available to download for free on Windows PCs and supports Minecraft Java Edition, Bedrock Edition is not supported. When it comes to mod loaders, both Fabric Mod Loader and Quilt Mod Loader are supported. It is also worth noting that it does not support the Forge Mod Loader.

How to Update Iris Shaders

Iris Shaders vs OptiFine

Both these mods perform the same functions. The major difference between them is the fact that Iris Shaders mod is open-source which many people can contribute to and modify, whereas OptFine is not. Hence it receives updates very quickly whereas OptiFine takes a long time to roll out a stable update.

It is also fairly newer compared to OptiFine which was released way back when the game first came out. It also relies on Sodium mod to deliver the performance boost in Minecraft whereas OptiFine can do this without relying on another mod. However, in its latest version, Sodium is automatically installed with it so now they’re essentially the same mod.

It can also instantly load shaders in-game, OptiFine on the other hand has to go through a load screen for a longer time. The majority of users also report getting better frames with Sodium compared to OptiFine. OptiFine on the other hand is more stable and supports a few extra shaders.

Iris Shaders Not Working

If it is not working for you, then we recommend uninstalling it completely and reinstalling it. Another possible fix is to install an older more stable version temporarily until an update fixes the issue for you.
