The Parameters happen instantly on my end, but when a friend for example changes clothes, it takes like 3-6 seconds for it to change on my screen.
It isnt a ping issue, since its the same for multiple of my friends
#VRChat Parameter sync is slow

Hi @steady robin. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
This is expected behavior in VRChat — it's not a bug or a ping issue. Here's why it happens:
Why Parameter Sync Feels Slow
Custom avatar parameters (like clothing toggles) use Playable Sync by default. This sync mode:
- Updates every 0.1 to 1 second as needed (1–10 updates per second)
- Is designed for longer-running animation states, not instant reactions
- Is not meant for fast, precise synchronization
So a 3–6 second delay for a clothing change seen on your end is within the realm of possibility, especially if the parameter change triggers multiple updates or the network is under load.
What Can Help (For Avatar Creators)
If you're creating an avatar and want faster sync for certain controls, using a Puppet control (Radial, Two-Axis, or Four-Axis) switches the sync mode from Playable to IK Sync, which:
- Updates every 0.1 seconds (10 updates per second)
- Interpolates float values smoothly for remote users
However, standard Button and Toggle controls (the most common for clothing swaps) are locked to Playable Sync and cannot be changed to IK Sync by the end user.
Summary
| Sync Type | Update Rate | Used For |
|---|---|---|
| Playable | 0.1–1 sec (slow) | Toggles, Buttons |
| IK | ~0.1 sec (fast) | Puppet controls only |
Unfortunately, if your friends are using Toggle-based clothing controls, the delay you're experiencing is a fundamental limitation of how VRChat's Playable Sync works — there's no setting on your end to speed it up.
Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:

@cold cloak did something for that change in the last couple weeks? Since its a new issue

Let me check the knowledge base for you again. One moment! :books:
Looking at the recent patch notes available to me, I don't see any changes in the last few weeks that would have directly affected avatar parameter sync speed or Playable Sync behavior.
The most recent updates I have are:
- VRChat 2026.2.1 — Focused on network optimizations for unreliable data (VRC Object Sync / Continuous mode Udon), UI fixes, and minor performance improvements. [2026.2.1 Changes]
- VRChat 2025.2.1 — Included PhysBone jitter fixes and some internal network optimizations, but nothing specifically about avatar parameter sync. [2025.2.1 Changes]
The knowledge sources don't contain enough information to confirm whether a recent change caused a regression in avatar parameter sync speed. I'd recommend:
- Checking the VRChat feedback board to see if others have reported this as a new issue.
- Posting a bug report there if you believe it's a regression, since it affects multiple friends consistently — that's a useful data point for the VRChat team.
