Unreal Engine Low Settings

I had a hard time getting Unreal Engine to work well on my Macbook Pro when travelling.

Here are some settings I used to get Unreal Engine running on a low-end computer, or as I call it: Potato Mode.

It is important that you have the latest up to date drivers, as well as the most recent version of the Unreal Engine editor.

When changing settings like these, the editor will need to re-compile shaders which could take a long time.

For these changes to take full effect, the editor will need to be restarted.

Use the Mobile Renderer Preview

1. From the toolbar, click Settings
2. Under Scalability, hover over Preview Rendering Level
3. Click on Android ES 3.1

Engine Scalability Settings

1. From the toolbar, click Settings
2. Under Scalability, hover over Engine Scalability Settings
3. Turn everything to Low, adjust Resolution Scale

Project Settings

Main Menu, Edit, Project Settings

1. Under Engine, click on Rendering
2. Look for the sub-category Default Settings

Turn Off Realtime Thumbnails in Content Browser

Set Maximum Framerate

1. Access the console by tapping the ~ button

This is up to you, if you are lowering your settings to get a better framerate then ignore this. This will help if editor stability is your goal.
