New ChatSystem seems to be causing high ping (possible memory leak)

Reproduction Steps

System Info

Device name LAPTOP-J50RUNH4
Processor AMD Ryzen 9 5900HX with Radeon Graphics 3.30 GHz
Installed RAM 16.0 GB (15.4 GB usable)
Device ID 59F62A39-C57A-4EC7-98BC-563D327BAFFB

|System type|64-bit operating system, x64-based processor|
|Pen and touch|No pen or touch input is available for this display|

**Reproduction: **

  • Enable for the ChatSystem the latest one
  • With (assuming it’s the InputBegan event) it begins a large stutter every key

Expected Behavior

When you play our game, the ping should be way lower. We’ve had to optimize our accelerator game like crazy, and finding out it’s from the new Chat System made us revert back and caused the ping to drop to a minimum of 70.

Actual Behavior

Ping is extremely high, reaching over 100 to sometimes 150 ms

Issue Area: Engine
Issue Type: Performance
Impact: High
Frequency: Constantly


By the new chat system, are you referring to TextChatService?


Yes! Switching the ChatSystem from Legacy to the newer one.


Got it, we’ll take a look into this. Thanks!


I have also had this issue on my game and on other games,
ping goes up like crazy and network receive becomes nonexistant for a couple seconds.

I wanted to mention that I’ve seen the ChatExperience core script take a lot of time in the microprofiler to run.

Specifically about Model GetBoundingBox and adorning the bubble.

The more players in game the longer it holds up the frame from the looks of it.
