Editor causes extreme CPU usage

Development Programming & Scripting UI

Starting a converted 4.11 project causes extreme CPU usage even in idle mode with deactivated realtime mode in the viewport. I’m using 4.12 preview from the Epic Games Launcher.

Interestingly the usage is about 60-70% if I’m in the viewport. If I open the project settings for example, it spikes to ~100%. Maybe its slate related?

EDIT: Also happens with a fresh 4.12 project!

Hi TriNityGER,

Please take a look over this post, I believe you are experiencing the same issue:

UE 4.12 P1 release looks terribly - Programming & Scripting - Epic Developer Community Forums

A fix has already been submitted for our Preview 2 update.
