Speed up immediate mode rendering in Minecraft

ImmediatelyFast

ImmediatelyFast is an open source Minecraft mod which improves the immediate mode rendering performance of the client.
It is designed to be lightweight and compatible with other mods.

Optimizations

ImmediatelyFast generally optimizes all immediate mode rendering by using a custom buffer implementation which batches draw calls and uploads data to the GPU in a more efficient way.
The following parts of the immediate mode rendering code are optimized:

• Entities
• Block entities
• Particles
• Text rendering
• GUI/HUD
• Immediate mode rendering of other mods

It also features targeted optimizations where vanilla rendering code is being changed in order to run faster.
The following parts of the rendering code are optimized with a more efficient implementation:

• Map rendering
• HUD rendering
• Text rendering

Performance

Here are some performance comparisons of areas the mod optimizes particularly well:

If other mods are listed in the table this means that this mod also optimizes that part of the game.

Test Hardware: Ryzen 5 1600, 32GB DDR4, GTX 1060

FPS Numbers were taken from external tools (in this case MSI Afterburner) and averaged over a couple of seconds.
If you decide to test this yourself keep in mind that ImmediatelyFast can only improve FPS in a scenario where your CPU is the bottleneck (Most likely the case if your GPU isn't ancient or you use very heavy shaders). Slower CPUs will benefit more from this mod than really fast CPUs.

Entity Rendering

Generally FPS should be around 2x higher on busy servers. [Tested using IF 1.1.7 on 1.19.3]

Tested on a spigot server with 1000 cows in a 3x3 box on screen.

Other mods	Without ImmediatelyFast	With ImmediatelyFast	Improvement
None	16 FPS	60 FPS	3.75x
Sodium	21 FPS	82 FPS	3.90x
Iris and Sodium	60 FPS	76 FPS	1.27x

Map Rendering

Generally FPS should be around 5x higher when there are many maps on screen. [Tested using IF 1.1.1 on 1.19.3]

Tested on a fabric server with the Image2Map mod and around 930 maps on screen.

Other mods	Without ImmediatelyFast	With ImmediatelyFast	Improvement
None	50 FPS	310 FPS	6.20x
Sodium	47 FPS	320 FPS	6.81x

HUD Rendering

Generally FPS should be around 40% higher in almost all scenarios. [Tested using IF 1.1.7 on 1.19.3]

Tested on a spigot server with different HUD elements on screen (Scoreboard, Potion effect overlay, Bossbars, Filled Chat, Extra hearts, Full Hotbar).

Other mods	Without ImmediatelyFast	With ImmediatelyFast	Improvement
None	250 FPS	380 FPS	1.52x
Sodium	335 FPS	630 FPS	1.88x
Exordium and Sodium	740 FPS	840 FPS	1.14x

Text Rendering

Generally FPS should be around 2x higher when there are many signs or holograms around you. [Tested using IF 1.1.7 on 1.19.3]

Tested on a spigot server with 200 signs (Filled with text) on screen.

Other mods	Without ImmediatelyFast	With ImmediatelyFast	Improvement
None	70 FPS	125 FPS	1.79x
Sodium	110 FPS	300 FPS	2.73x

Block-Entity Rendering

Generally FPS should be around 20% higher when there are many block entities around you. [Tested using IF 1.1.7 on 1.19.3]

Tested on a spigot server with 400 chests on screen.

Other mods	Without ImmediatelyFast	With ImmediatelyFast	Improvement
None	170 FPS	205 FPS	1.20x
Sodium	315 FPS	410 FPS	1.30x

Compatibility

ImmediatelyFast is structured to interfere with mods as little as possible. It should work fine with most if not all mods and modpacks.

Known incompatibilities:

• OptiFabric / OptiFine

immediatelyfast's Issues

Another incompatibility with YTTR (F3 screen)

F3 screen doesn't show any text when both YTTR and ImmediatelyFast are present. It works fine with either of them, it doesn't when the two are together.

ImmediatelyFast-1.19-1.1.2
yttr-7.638+1.19.2

Some items with custom models are invisible in hotbar

Its already happened before, but one of the updates fixed it; after updating from 1.1.5 to 1.1.6, the issue came back.
This happens with things like Yttr's Rifle or with Wrench from Create.

The level is not displayed correctly

After my tests, it seems that when ImmediatelyFast and an optimized module called Caxton installed together, the level display will be separated from the taskbar and placed at the bottom of the taskbar (I installed the Raised module, this module can raise and lower the taskbar, and the level display will not move together when I raise and lower the taskbar)

The first image shows the installation of ImmediatelyFast-1.1.10+1.19 and caxton 0.4.0 beta. 4+1.19.2 together

The second image only installs ImmediatelyFast-1.1.10+1.19

The third image only installs caxton-0.4.0-beta.4+1.19.2

Titles are not visible behind chat box when using ImmediatelyFast and Title Fixer

I was able to reproduce this with these steps:

1. Installed clean fabric instance with mods ImmediatelyFast, Title Fixer and Cloth Config API (required by Title Fixer).
2. Created a new world and spammed the chat until it was full of messages.
3. Used command: /title @a title "Title text is not showing up behind chat box."

Result:

Without ImmediatelyFast:

Fabric/Mod versions:

Minecraft 1.19.3
Fabric loader 0.14.14
ImmediatelyFast 1.1.8
Title Fixer 1.0+1.19.3
Cloth Config 9.0.94

Update to support new sodium 0.4.9

as stated in the new version of sodium, immediatelyfast need an update
https://www.curseforge.com/minecraft/mc-mods/sodium/files
NOTE: This version makes internal changes that will likely break mods that try to hook into Sodium (such as Iris, Indium, ImmediatelyFast, etc.) You will need to wait for an updated version of these mods.

Horse Markings Flickering While Using ImmediatelyFast

Versions

• Minecraft: 1.19.2
• Quilt Loader: 0.17.6
• ImmediatelyFast: 1.0.4

Description

When using this mod, I have noticed that certain layered textures, such as the different markings on horses, flicker in and out of existence while moving around the origin of the texture. This was tested with no other mods and can be easily replicated by simply spawning some horses with a variety of markings (a simple spawn egg works) and walking/flying around them while looking at them.

Placed banners all appear completely white

As title says. All banners placed in a world appear completely white, no matter what patterns they had, or even if white wasn't their base color. The patterns do appear on the item, however.

Blank.banners.mp4

Mod version: 1.0.6
Minecraft version: 1.19.3
Fabric version: 0.14.11
Processor: Intel i5-1240P with integrated graphics

Incompatibility with Yttr

Opening Yttr's creative tab and clicking on Mechanisms category (Sometimes can take more than one attempt) causes most entities to turn red as if they were hit and had immunity frames.

High fps drops with REI.

Mod breaks text and GUI rendering on servers with custom resource pack

Encountered these issues on the Server Origin Realms, where text and GUI elements (I assume the GUI element also was text) were broken while this mod is active.

With mod active:

Without the mod:

The server is utilizing a custom resource pack, which also alters some vanilla core shaders. It does not use any kind of server mods. Only plugins.

Having HUD batching enabled causes `IllegalStateException` log spew when Slight GUI Modifications is simultaneously installed.

Reproduction steps

1. Install all the mods listed above, and make sure hud_batching is set to true in the ImmediatelyFast prefs.
2. Join a test server or a singleplayer world.
3. Open chat.
4. Enjoy log spew so frequent (probably firing every frame) that it noticeably slows down client performance.

Workarounds

• Set hud_batching to false in the ImmediatelyFast prefs.

Conflicting mixins with Porting-Lib causes game crash

Mixin Conflict Helper, by isXander warned me of an issue between your mod and https://github.com/Fabricators-of-Create/Porting-Lib .
Here's the log:
2022-12-27-3.log

Crash with Iris and ImmediatelyFast

https://mclo.gs/0IBicIg

How to reproduce:

1. Launch minecraft with Iris, Sodium and ImmediatelyFast (all latest versions on 1.19.3)
2. Try to change a shaderpack setting before joining a world

Shifting in second + third person causes holograms to become less visible

In vanilla, I can confirm that this is not the case.

Black text with Wynntils

When using Wynntils, some of the text Wynntils renders appears black. As well as the vanilla item count number. This was extremely finicky to reproduce and required multiple relogs / reboots sometimes but I'm fairly certain the incompatibility is between only IF and Wynntils.

Horse patterns show through horse armour

CurseForge upload

I dislike CF, but somebody had to do this job..

Why?

• Most people use CF -> More popularity for the mod
• CurseForge rewards -> You get paid

Hi, are you considering making backports for older minecraft versions?

I think I found an incompatibility with iris and I don't know if that causes crashes 1.19.2

AppleSkin exhaustion underlay appears in front of hunger bar

If I have ImmediatelyFast-1.1.8+1.19.3 loaded with appleskin-fabric-mc1.19.3-2.4.2 (and fabric-api-0.73.2+1.19.3) the exhaustion underlay appears in front of the hunger bar instead of behind it:

If I turn off ImmediatelyFast, it goes back to normal. This seems to be the same issue as this reddit post. If you need any logs or something else from me, I can provide them.

Some optimizations

I ran spark profiler, maybe some parts could be optimized?

Minecraft crashed!

I've built a small piston contraption and by activating it Minecraft crashed with potential causes coming from More Culling, Indium and Sodium. However after disabling your mod, it didn't crash and by enabling the mod again I could reproduce the crash. I'm not sure if it's really related to your mod, because after some further testing I could not reproduce the crash anymore.

Detect modified core shaders and disable HUD batching

Prevent issues with servers which modify the core shaders to remove/change certain UI elements. Those shader modifications are not compatible with batched rendering and need to be ran per element

Player list renders weird on MCC Island

When playing on the server play.mccisland.net with the newest version of ImmediatelyFast (1.1.8 for 1.19.2) the player list is bugged.

This is what it looks like with ImmediatelyFast 1.1.8

This is what it looks like without ImmediatelyFast 1.1.8

Iris Shader crash

Minecraft will crash when u turn on shaders and then try to turn them off

[1.19.4] Armor trims not rendering with certain combinations of equiped slots.

Observed behavior:

• Using trimmed helmet and boots works correctly;
• Adding trimmed leggings removes trims on helmet and boots;
• Adding trimmed chestplate returns helmet and boot trims, but removes trim on leggings;
• For any step adding not trimmed equipment doesn't affect the result;
• Starting point includes both helmet and boots, but same issue occurs if only one is equipped;
• Screenshots demonstrate issue on armor stands, but it also works on players and other entities;

Testing setup:

Tested on 1.19.4 on fabric loader 0.14.17 and only mod being loaded is ImmeaditelyFast 1.1.10

Crashes in a modpack with many mods

My Minecraft Version: 1.19.4 with Quilt Mod Loader 0.19
Crash Log:https://mclo.gs/mL2p48D
Full Log:https://mclo.gs/36CRSb4
By the way, I'm the author of this modpack, and I don't know which mod it conflicts with. 😥

Warns about missing Armor Chroma

Upon start up, the following warning is printed to the log:
[17:24:52] [main/WARN]: Error loading class: nukeduck/armorchroma/GuiArmor (java.lang.ClassNotFoundException: nukeduck/armorchroma/GuiArmor)

Mods:

• Fabric Loader 0.14.14 for Minecraft 1.19.2
• ImmediatelyFast-1.1.8+1.19.jar
• sodium-fabric-mc1.19.2-0.4.4+build.18.jar

I would guess this is resolved by installing the Armor Chroma mod, but when not intending to use the mod the warning clutters the log somewhat.

Very minor "issue", fully understand if you won't prioritize fixing it 😄

Frame rate issues with latest version of ImmediatelyFast on the MCC Island server.

Hello, I have the Fabulously Optimized mod pack installed (mod pack version 4.7.1), and I just recently updated ImmediatelyFast to the latest version through Check for Updates in Curseforge. After installing the latest version of your mod, I went onto the MCC Island server and I immediately started having frame rate issues. So I uninstalled the mod pack and reinstalled it to revert the latest update of ImmediatelyFast, and I no longer have any performance issues. So it has to be something to do with the latest version of
ImmediatelyFast.

MCC Island has a bunch of custom entities which is probably related to the issue I am having.

What might also be worth mentioning is I always have Vsync enabled (75 FPS, 75hz monitor). I will share my in-game options file, not sure if it will help out though.

Issue with Status Effect Bars

The bars on the HUD don't show up
The mod: https://modrinth.com/mod/status-effect-bars

Optimize FPS limit

Is it possible to optimize FPS limit to better hold it's value? For example without the limit I have 300 fps, but with 250 FPS limit I have around 220.

Does ImmediatelyFast make having Enhanced Block Entities pointless?

Heya! Does having both this mod and Enhanced Block Entities redundant? Since they both optimize block entities

Incompatible with Tubet

In the Tubnet server, when playing the game Light Stryke, I can´t see how many players are left in the enemy team in the top menu. Plz fix. The server IP is tubet.gg
In the images the one that only shows how many people are left on my team I have the mod installed.

Rendering glitch with Xaero's Minimap

I'm testing using the latest versions of Xaero's and ImmediatelyFast on 1.19.2. I have not tried this in a standalone instance yet to confirm the issue still happens there. Other potentially important mods are Sodium, Exordium, and Flywheel.

Incompatibility with VulkanMod

Hello, just suggesting this incompatibility be added to the list. Not expecting a fix, the game crashes after the Mojang studios logo pops up.

How does IF optimize block entities and is it compatible with EBE?

Also, is it compatible with Exordium (FasterGUI)?

The "Force Unicode Font" setting is broken

Optimize server pinging and joining

The bug is described here, basically when you have couple servers in your list and you ping them, pinging won't work and you won't be able to join a server for some time.
https://bugs.mojang.com/browse/MC-125762

[Feature] Config System

It would be beneficial if there was some method of disabling certain optimizations of immediately-fast.

For example, the gui batching can cause performance issues on older GPUs, I myself have not experienced this issue but others have reported issues with it, much like exordium.

This can be done in two ways, a simple file config like sodium or a more user-friendly config like Debugify.

You could also address this issue by actually fixing the performance problems with older GPUs for gui batching, or even disabling it if an old GPU is detected.
