ImmediatelyFast is designed around rendering optimization, including entities, block entities, particles, text, GUI/HUD elements, and other immediate-mode rendering. Dynamic Lights instead makes supported items and entities emit light while they are held, worn, dropped, or otherwise supported.
What Is ImmediatelyFast?
ImmediatelyFast is an open-source Minecraft performance mod designed to make immediate-mode rendering more efficient. It uses custom buffering and batching techniques to reduce rendering overhead and improve the way data is sent to the GPU.
The mod can optimize several rendering categories, including:
- Entities
- Block entities
- Particles
- Text
- GUI and HUD elements
- Immediate-mode rendering used by other mods
Its purpose is therefore fundamentally different from a lighting mod. ImmediatelyFast does not add portable illumination to Minecraft; instead, it attempts to make existing rendering operations more efficient.
ImmediatelyFast Performance
Performance improvements depend heavily on the Minecraft version, hardware, resolution, installed mods, and the type of content being rendered.
Developer benchmarks have reported substantial improvements in specific scenarios. For example, tests involving large numbers of signs showed higher FPS with ImmediatelyFast, while block-entity-heavy scenes also showed measurable gains. These figures are benchmark results rather than universal FPS guarantees.
ImmediatelyFast can therefore be particularly relevant when a Minecraft installation contains:
- Many block entities
- Large amounts of text
- Numerous particles
- Complex HUD elements
- Mods that perform significant immediate-mode rendering
What Is Dynamic Lights?
Dynamic Lights is designed to add dynamic illumination to Minecraft. Supported items and entities can emit light when they are held, worn, dropped, or otherwise placed in supported situations.
The Tschipcraft implementation supports more than 50 vanilla items out of the box and provides several light levels, including 3, 6, 9, 12, and 15.
Examples of supported lighting sources include:
- Torches
- Lanterns
- Glowstone
- Enchanted items
- Certain armor
- Items carried by mobs
- Items in item frames
- Other supported entities and objects
Some special behavior is also available for enchanted equipment and certain item effects.
Feature Comparison
Rendering Optimization
ImmediatelyFast has a clear focus on rendering efficiency. Its custom buffer implementation batches rendering operations and is designed to reduce unnecessary GPU and CPU overhead.
Dynamic Lights does not primarily target rendering optimization. Its main purpose is to create the visual and gameplay effect of movable light sources.
Difference: ImmediatelyFast is a performance-oriented rendering mod, while Dynamic Lights is a lighting-functionality mod.
Dynamic Lighting
Dynamic Lights has the advantage in this category because dynamic illumination is its core feature.
A player can carry a supported light-emitting item without placing a permanent torch in every location. Supported mobs, dropped items, and other entities can also participate in the lighting system.
ImmediatelyFast does not provide this functionality.
GUI and Text Rendering
ImmediatelyFast specifically optimizes text and GUI/HUD rendering. This can be useful on servers, modpacks, or resource-heavy setups where a large amount of text or interface content is displayed.
Dynamic Lights has no comparable GUI or text-rendering optimization.
Mod Compatibility
ImmediatelyFast is designed to interfere with other mods as little as possible and supports Fabric, Forge, NeoForge, and Quilt in its current compatibility listings. Known incompatibilities include OptiFabric/OptiFine and some closed-source clients such as Lunar Client and LabyMod.
Dynamic Lights has versions for several mod loaders, although exact support depends on the Minecraft version and implementation. The Tschipcraft project currently lists Fabric, Quilt, NeoForge, and Forge support, with Forge support having version-specific limitations.
Installation and Requirements
ImmediatelyFast
ImmediatelyFast is installed as a Minecraft mod and requires a compatible mod loader and Minecraft version. Current project listings include support for recent Minecraft versions and loaders such as Fabric, Forge, NeoForge, and Quilt.
The basic installation process is:
- Install the appropriate Minecraft mod loader.
- Download the ImmediatelyFast version matching the Minecraft version.
- Place the .jar file in the mods folder.
- Launch Minecraft.
- Adjust configuration options if necessary.
ImmediatelyFast also provides configuration options for certain rendering-related behaviors.
Dynamic Lights
The Tschipcraft implementation can be installed as either a mod or data pack. The data-pack approach places the downloaded pack into the world’s datapacks folder, while the mod version is placed in the Minecraft mods folder. MidnightLib can additionally provide a global settings interface for the mod.
One notable characteristic is that the Tschipcraft Dynamic Lights implementation is designed to operate server-side. Players joining a server with it installed do not necessarily need to install the mod themselves for the server-side lighting behavior to work.
Performance Differences
The two mods affect performance in different ways.
ImmediatelyFast is specifically intended to improve rendering efficiency. Its impact can be noticeable in scenarios where the game or other mods generate many immediate-mode rendering operations. However, results vary according to the system and workload.
Dynamic Lights adds additional lighting behavior rather than acting as a general-purpose FPS optimization. The server-side implementation uses light blocks and has inherent limitations because the lighting system is tied to Minecraft’s block grid.
Dynamic lighting can also introduce additional processing depending on how many moving light sources are present.
Compatibility and Limitations
ImmediatelyFast Limitations
Important considerations include:
- It is focused on rendering rather than adding gameplay features.
- Results vary between systems.
- Some rendering-related mods or clients can conflict with it.
- OptiFabric/OptiFine are listed among known incompatibilities.
- Some closed-source clients can also cause compatibility issues.
Dynamic Lights Limitations
Dynamic Lights has a different set of limitations:
- Dynamic light positions are restricted by the light-block system.
- Lighting can appear less smooth while moving.
- Certain 1×1 spaces cannot accommodate the required light blocks.
- Some shader packs that do not use the vanilla lightmap may not display the dynamic lighting correctly.
- Older Minecraft versions can have additional block-update-related behavior.
These limitations are important for heavily modded environments and shader-based setups.

Can They Be Used Together?
Because they address different areas of Minecraft, ImmediatelyFast and Dynamic Lights are not inherently alternatives in terms of functionality.
A Minecraft setup can potentially use a rendering optimization mod alongside a dynamic-lighting solution, provided the specific Minecraft version, mod loader, shaders, and other installed mods are compatible.
However, compatibility should always be checked against the exact versions being used. ImmediatelyFast documents specific incompatibilities, while Dynamic Lights implementations can have their own limitations depending on whether the mod, data pack, or another dynamic-lighting solution is being used.
