Particle Limiter

VRChat has introduced a Particle Limiting System on June 19, 2018. This Feature allows you to limit the maximum values of particle specific settings without completely hiding them through the trust system.

This means that you are still able to see most particle animations while having a smaller risk of being crashed or obtaining lagg.

To use the Particle limiter system, add a file called config.json to %AppData%\..\LocalLow\VRChat\vrchat and give it the following content:

Do not set any of these values to 0! It can cause avatars to fail loading and load the red error model instead!

Please keep in mind you will need to restart your game for changes to take effect.

Limiter Configuration Description

Value Name	Explanation
betas	Adding or removing the string "particle_system_limiter" will enable/disable the Limiter system
ps_max_particles	Max particles a single particle system can spawn
ps_max_emission	Max emission a single particle system is allowed
ps_max_total_emission	Max emission allowed between all particle systems on an avatar
ps_mesh_particle_divider	The mesh particle penalty is calculated using the highest poly mesh on them divided by this value, the resulting value divides the max particle allowance for the particle system
ps_mesh_particle_poly_limit	The max poly count a mesh on a particle system can be
ps_collision_penalty_high	The penalty for high quality collision on a particle system, the resulting value divides the max particle allowance for the particle system
ps_collision_penalty_med	The penalty for medium quality collision on a particle system, the resulting value divides the max particle allowance for the particle system
ps_collision_penalty_low	The penalty for low quality collision on a particle system, the resulting value divides the max particle allowance for the particle system
ps_trails_penalty	The penalty for having trails enabled on the particle system, the resulting value divides the max particle allowance for the particle system
