OptiFrames
by lukebrl
OptiFrames is a Fabric client mod that changes how item frames holding large map displays are drawn, aiming to reduce the frame rate cost of those displays.
What it does
OptiFrames targets the rendering of map displays built from many item frames. It packs map textures into a shared atlas, which lowers the number of GPU draw calls needed to show a large map, and it hides the redundant borders between adjacent maps. The author reports up to a 9x frame rate increase with large maps, and notes that demanding scenes gain the most. Map markers, banners and other icons keep drawing as normal.
The mod is configured through Mod Menu, and Cloth Config API supplies its settings screen. Options cover the frame render type (vanilla or optimized frame model rendering), frame border rendering, back face rendering of item frames, and the atlas size, where 4096 is the default and a larger atlas fits more maps into each draw call. OptiFrames can also be turned off entirely. Fabric API is required, and the author says the mod works well with Sodium and Iris. Tests with Sodium showed similar gains without OptiFrames.
Files exist for 1.21.11 and 26.1 on Fabric only, with 3.1.0 for 26.1 as the latest file, published 2026-03-29. Only the client runs the mod, so servers do not need it. The mod is released under the Creative Commons Attribution Non Commercial 4.0 license and is not open source, though its source code is public.
Key features
Shared map texture atlas
Map textures are packed into one shared atlas, so large map displays need fewer draw calls.
Border hiding
Redundant borders between adjacent maps are hidden, which removes work from the frame rendering pass.
Frame render type setting
Players choose between the vanilla item frame model and an optimized model for frame rendering.
Configurable atlas size
The atlas texture size can be raised to fit more maps per draw call, with 4096 as the default.

How it compares
FPSFlow is client-side only, open source under the GNU Affero General Public License v3.0 only, and published for Fabric across 1.21.11 – 26.2. Map Art Lite is also client-side only and published for Fabric across 1.21.6 – 1.21.11, but it is not open source and is under the MIT License. Dynamic Views targets only 26.1.2, is client-side only, and is released under All rights reserved, so it is not open source.

What the author says
A lightweight, client-side Fabric mod that makes large map displays render cleaner and smoother without changing their appearance. Test are made with Sodium but you can expect same gain without it.
