UE4.27 Stutters on the M5

Development Programming & Scripting

Hello @arts.x ,

I don’t have a MacBook Pro M5, but I did some research and found a few things that might help resolve the issue.

One of the most common solutions, and the one that worked for many users, is exactly what you already did: disabling the “UDP Messaging” plugin. In addition to that, you could also try disabling the Telemetry plugin, as some users reported improvements after doing so.

Another thing you could try is adjusting the Editor Scalability Settings, as this has helped improve editor stability in some cases.

You could also try verifying the project or running it as an administrator. It might be worth a try, as it has helped in some cases.

Finally, I found a few posts that might be useful as a reference or provide other possible solutions to the problem.

Hope it helps!
