OptiFrames

OptiFrames

A lightweight, client-side Fabric mod that makes large map displays render cleaner and smoother without changing their appearance.

Performance Test with 40×40 and 70×70 map

Test are made with Sodium but you can expect same gain without it.

Why use OptiFrames?

• Optimized rendering: hides redundant borders between adjacent maps.
• Texture Atlas: all map textures are packed into a shared atlas, drastically reducing GPU draw calls.
• FPS boost: expect up to 9x FPS increase with large maps.
• Map decoration support: player markers, banners, and other map icons still render correctly.
• Lightweight: designed to work well alongside Sodium and Iris.

Installation

1. Download the latest optiframes-<version>.jar from the Modrinth/Curseforge page.
2. Place the JAR in your mods folder.
3. Start Minecraft using a Fabric profile.

Configuration

You can configure the mod with Mod Menu:

• Enable/Disable Optiframes entirely.
• Frame Render Type — choose between vanilla and optimized frame model rendering.
• Frame borders — toggle frame border rendering for extra performance.
• Back Face Rendering — toggle rendering of item frames back face.
