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

1. Community signal: The issue is now tracked in a Roblox Developer Forum (DevForum) topic, ID 4542300.
2. Repro pattern: Open Studio -> wait a few minutes -> camera gets choppy -> delays show in editor actions.
3. Scope hint: It happens on fresh baseplates too, so this does not look like one broken project file.
4. 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.

FAQ

  A: The report says it can happen on a baseplate, so it is not only about big maps.

• Q: What is the quickest temporary fix right now?
  A: Restart Roblox Studio when performance drops.
• Q: What should I attach if I report the same bug?
  A: Repro steps, ISO date/time, system info, microprofiler dump, and logs if staff asks.
• Q: Is there a confirmed fixed Studio version as of 2026-03-28?
  A: No confirmed fix version is shown in the provided thread snapshot yet.
