Unity Particle System vs VFX Graph: Which Should You Use?

By Eric VFX Studio · Published 2026-10-09

QUICK ANSWER

Use the Particle System when you need the Built-in Render Pipeline, WebGL, low-end mobile, VRChat, physics collisions, or per-particle control from C#. Use VFX Graph when your project uses URP or HDRP on hardware with compute shaders and you need very large particle counts or GPU features such as signed distance fields. Many projects use both.

The main difference: CPU vs GPU

The Particle System (sometimes called Shuriken) simulates particles on the CPU and is set up with modules in the Inspector. VFX Graph simulates particles on the GPU with compute shaders and is built in a node-based graph. That one difference explains most of the others: VFX Graph can move far more particles, but it needs a render pipeline and hardware that support it, and its particle data stays on the GPU, so it can’t react to physics or scripts the way the Particle System can.

Side-by-side comparison

	Particle System	VFX Graph
Simulation	CPU	GPU (compute shaders)
Editing	Modules in the Inspector	Node-based graph
Render pipelines	Built-in, URP, and HDRP	URP and HDRP
Platforms	All Unity platforms, including WebGL and low-end mobile	Platforms with compute shader support; not WebGL
Practical particle count	Hundreds to a few thousand per system	Hundreds of thousands to millions
Collisions	Physics colliders, with collision and trigger callbacks in C#	Simple shapes, signed distance fields (SDF), and the depth buffer
Scripting	Read and write individual particles from C#	Exposed properties and events; per-particle data stays on the GPU
Lights, trails, sub-emitters	Built-in modules	Particle strips for trails, GPU events for spawning
VRChat	Supported	Not supported

Particle counts are typical ranges; real limits depend on the effect, the target hardware, and the rest of your game.

When to use the Particle System

Your project uses the Built-in Render Pipeline, or you are making VRChat avatars or worlds.
You target WebGL or a wide range of mobile devices, including low-end phones.
Particles must collide with physics colliders or trigger gameplay events in C#.
The effect needs lights, sub-emitters, or per-particle scripting.
The effect is a typical gameplay effect, such as a hit, slash, buff, or pickup, with a modest number of particles.

When to use VFX Graph

Your project uses URP or HDRP and your target platforms support compute shaders (PC, consoles, and modern mobile devices).
You need tens of thousands to millions of particles, such as dense magic auras, swarms, sparks, or ambient particles.
You want GPU features like signed distance fields, point caches, or particles that form a 3D model.
You prefer a node-based workflow with exposed properties that artists can tweak per instance.

Mobile, WebGL, and VRChat

Platform support is often what decides the question. VFX Graph needs compute shaders, so it does not run in WebGL builds, and on mobile it only works on devices with compute shader support. Even then, test performance on real hardware. VRChat does not support VFX Graph, so VRChat effects are made with the Particle System. If you are unsure about your targets, the Particle System is the safe default.

Can you use both?

Yes. In a project that uses VFX Graph you can still use the Particle System and mix them freely: keep gameplay effects that need collisions or scripting in the Particle System, and use VFX Graph for large showcase or ambient effects. Both can use materials made with Shader Graph.

FAQ

Is VFX Graph better than the Particle System?

Neither is better in every case. VFX Graph is better for very large particle counts and complex GPU effects, especially in URP or HDRP. The Particle System is better when you need the Built-in Render Pipeline, WebGL, low-end mobile, VRChat, physics collisions, or per-particle control from C#.

Which render pipelines does VFX Graph support?

VFX Graph supports URP and HDRP. The Particle System works in the Built-in Render Pipeline, URP, and HDRP. VRChat does not support VFX Graph, so VRChat effects use the Particle System.

Should I use VFX Graph for mobile games?

Only if your target devices support compute shaders and you test performance on real devices. For the widest device support, especially low-end phones, the Particle System is the safer choice.

Can I use the Particle System and VFX Graph in the same project?

Yes. Many projects use both: the Particle System for gameplay effects that need collisions or scripting, and VFX Graph for large ambient or showcase effects.

Which should beginners learn first?

Start with the Particle System. It works in every render pipeline and on every platform, and its modules teach the basics of emission, lifetime, color, and size. The same ideas carry over to VFX Graph.

Can VFX Graph particles collide with physics colliders?

Not directly. VFX Graph collides with simple shapes, signed distance fields, and the camera depth buffer, all on the GPU. If particles must hit physics colliders or trigger C# events on contact, use the Particle System.
