Since the implementation of the new TextChatService, our game has been experiencing significant performance issues. Specifically, every time a player sends a message, the game freezes for most players or makes their FPS drop. This issue intensifies when players open the chat to view messages, leading to severe lag and an unplayable moment since the FPS drop to around 10.
Unfortunately it looks like everyone has this problem with text chat service. I think Roblox made an optimisation update a few days ago and they’re trying to optimise this more.
I also have the same issue! I was wondering why my phone kept stuttering recently. This issue was also present in the old chat service until they fixed it, so maybe it has to do with something similar in their end. For now, we could only wait for them to fix it unfortunately.
