Breeze Flow Shaders do Minecraft 1.21.1, 1.21

BreezeFlow is a modified edition of Complementary Shaders for Minecraft Java Edition, created to preserve its exceptional attention to detail, quality, and optimization while pushing a more cinematic, realistic look at higher frame rates on weaker devices. Complementary Shaders began as an edit of BSL Shaders in 2018 and has since evolved through countless major updates, community feedback, and a full rewrite to meet modern standards; BreezeFlow is built on that legacy and gives full credit to the original project.

BreezeFlow’s mission is simple: keep the signature Complementary look and polish, but make it run smoother on integrated GPUs and lower-end systems without sacrificing atmosphere. It is designed to feel cinematic and immersive while remaining practical for everyday gameplay.

There are many optimizations done, too many to be listed. However most of the work was based on reducing the amount of calculations performed and a LOD system was implemented.

All credits go to the original shader Complementary Shader

This shader is simply a variant of Complementary with optimization changes and color grading changes alongside new features.

An example of a new feature (Meteor Showers):

Better Nebula:

I highly recommend checking out the gallery page to understand how the shader looks - many gallery pictures are only at low preset and will look better at higher presets.

Like all shaders, Sodium and Iris or Optifine is required. I recommend using the mods listed as well.

• Fps at 1080p:
• Potato: 75-113 fps
• Very Low: 65-100 fps
• Low: 65-87 fps
• Medium: 45-70 fps
• High: 40-60 fps
• Very High: 39-59 fps
• ULTRA: 25-39 fps

• Device Info:
• Cpu: i7-13700H
• Gpu: Integrated Iris Xe Graphics
• Memory: 16 GB
• Fabric 1.21.10

Mods Used:

Intellium: Improves CPU and GPU workload to further optimize performance on Intel GPU's. Only works on Intel GPU's and is made by me. The mod may not be published yet when you are viewing this page.

C2ME: Improves world generation and chunk loading by using multiple CPU threads, making terrain load faster and reducing lag.

Cloth Config Api: A library mod that provides config menus for other mods. Doesn’t do anything on its own.

Entity Culling: Stops rendering entities you can’t see (like ones behind walls), improving FPS.

Fabric Api: Core library required for most Fabric mods. Adds hooks and systems mods depend on.

FerriteCore: Reduces memory usage, especially RAM, helping performance and stability.

ImmediatelyFast: Speeds up UI and rendering performance, especially menus and HUD elements.

Iris: Adds shader support to Fabric (lets you use shaders like OptiFine does).

Lithium: Optimizes game logic (AI, physics, ticking), improving overall performance.

Mod Menu: Adds a menu to view and configure installed mods in-game.

Nosium-Forked: Optimizes world generation noise calculations, improving chunk generation speed.

RenderScale: Lets you render the game at a lower resolution and upscale it for better performance.

Sodium: Major rendering optimization mod that significantly boosts FPS and reduces lag.

If you are not getting similar fps it may be due to the resolution, use the mod Render Scale to reduce your resolution to get higher fps.

The Default is also Very Low, reduce it to Potato if you are not getting your target fps

Again huge thanks the original shader Complementary Shader

Without it this project wouldn't exist.
