About

AsyncParticles

It will remain in the beta stage in the future to alert potential mod conflict issues.
Now compatible with Particle Core(v20.1+).
Now compatible with Valkyrien Skies v2.4.

Core Features

GPU Acceleration

Offloading partricle vertex transformations to the GPU reduces per-frame data uploads to the GPU, lowers CPU load, and improves frame rates.
This essentially replaces the previous async partricle vertex extraction while also improving compatibility (async partricle extraction is now disabled by default).
Fill 1331 campfires (16,000+ particles, you can change the limit via config screen):
Tested on: Ultra5 225H + RTX 5060 Laptop, 1080p.

Create Integrations

Create contraptions can now block vanilla weather.(v20.1.0a+)
- Will move this to a new mod when I get free time.
Particles can now collide with contraptions.

Other Features

Flexible mixin options.
Minecraft
- Particle culling.
- Async particle tick.
- Async particle light cache.
- Delayed texture tick by one frame to reduce client tick duration.

Configuration

Settings can be accessed via the ModList/ModMenu.

Troubleshooting

We've introduced Diagnostics, not applying the recommended settings usually won't cause a crash, you'll get a prompt in the chat bar to change them.

Use with Bosses Rise

Enable GPU Only Async Particle Tick.

Use with BadOptimizations

Set enable_particle_manager_optimization: false in badoptimizations.txt
Fixed since 20.1.1.0/21.1.1.0.

Crash with C2ME

Set enforceSafeWorldRandomAccess = "false" in c2me.toml
- Only set this if you are experiencing crashes.

Crash with LodestoneLib

Set buffer_particles = false in lodestone-client.toml.

Crashes related to `ClassInstanceMultiMap` or `Level.getEntities(...)`

Please share the logs or crash report on the GitHub issue.
As a workaround, enable the option:
Mixin → Make 'ClassInstanceMultiMap' Thread-Safe

Crashes related to `Level.getBlockEntity(...)`

Please share the logs or crash report on the GitHub issue.
As a workaround, enable the option:
Mixin → Make 'LevelChunk#blockEntities' Thread-Safe

ConcurrentModificationException

The Most Common Cause

This exception typically occurs when particle rendering and ticking concurrently access the same thread-unsafe container.

How to Fix

Add the fully qualified particle class names to both particle$lockProvider and particle$lockRequired in the mod's Mixin settings.
See the configuration guide for details

Note: This enables fine-grained locking for specific particle types, allowing safe asynchronous execution between the tick() and render() methods.

Other Potential Causes

Starting in vX.4.0, the default particle rendering mode has been changed to SYNCHRONOUSLY to prevent rare ConcurrentModificationExceptions when used with mods that access external thread-unsafe containers (e.g., global maps or lists) during particle rendering.

If you're using an older version (≤ vX.3.0), consider manually setting the mode to SYNCHRONOUSLY in the config screen for improved stability.
For modpack authors: If you’d like to test whether FASTEST provides a noticeable FPS boost in your setup, you can switch to it in the config screen—but use with caution, as it may trigger crashes with incompatible mods.
