Roblox · Sat Mar 28, 2026 5:22 am

Quick Summary

On 2026-03-28, a report says Roblox Studio, the creation app from Roblox Corporation, starts smooth and then gets laggier the longer it stays open.
The post says new baseplates, cache reset, and closing Explorer/Properties/Output only slow the lag down. It still comes back.
As of 2026-03-28, the shared thread snapshot shows 3 posts and 2 participants, with Studio restart used as a temporary reset.

What's New

Community signal: The issue is now tracked in a Roblox Developer Forum (DevForum) topic, ID 4542300.
Repro pattern: Open Studio -> wait a few minutes -> camera gets choppy -> delays show in editor actions.
Scope hint: It happens on fresh baseplates too, so this does not look like one broken project file.
Hardware context shared: Intel Core i5-8400, Intel UHD Graphics 630, Radeon RX 480, and 16 GB RAM.

This is a bug-status style update, not a new feature drop.

Developer Context
Roblox bug-report rules explain why this kind of issue can take time to fix. On 2019-07-20, Roblox said lag reports should include a microprofiler dump and full system info, so engineers can reproduce the slowdown and target the real bottleneck.

For lag/slow bugs, include microprofiler dump and system information.
If Roblox staff asks for logs, Studio logs are in `%localappdata%\Roblox\logs` on Windows.
Fixes are usually shipped in versioned release notes (example: "Release Notes for 635" posted on 2024-07-25).

Why You Should Care

Long build sessions get interrupted, and that kills your flow.
More restarts means slower game updates for your players.
Good bug reports from creators can help Roblox fix this faster for everyone.
