There are a lot of things that make Unreal appealing in an education environment–it’s free for most purposes, it’s open source, and it has great Linux support–but a common stumbling block is its performance out of the box on lower-end desktop systems with iGPUs, MacBooks in particular. Fortunately Unreal is perfectly capable of running smoothly on almost any 2010s machine if set up properly.<\/p>\n

Step 1.<\/b> If you’re starting from scratch, run the Epic Launcher and go to the Unreal Engine<\/b> tab.
<\/p>\n

Step 2.<\/b> Click Install Engine<\/b>.
<\/p>\n

Step 3.<\/b> Unreal is huge; the full install is about 30GB. If you need to save on disk space, click Options<\/b>.
<\/p>\n

Step 4.<\/b> Uncheck Android<\/b> and iOS<\/b> if you don’t need to build for those platforms.
<\/p>\n

Step 5.<\/b> You’ve now cut the disk space usage nearly in half.
<\/p>\n

Step 6.<\/b> Once Unreal is installed, it will start at this New Project Categories<\/b> screen, which will take you through steps 7–9 one after the other. The project category determines what templates you’ll see—Games<\/b> is the default category and is fine to start with.
<\/p>\n

Step 7.<\/b> Here we’ve chosen a First Person<\/b> template.
<\/p>\n

Step 8.<\/b> Now here comes the important part: in the Project Settings<\/b>, under Choose the performance characteristics…<\/b>, choose Scalable 3D or 2D<\/b>. This is the “low-end” graphics option.
<\/p>\n

Step 9.<\/b> For mobile projects, you can quickly gain a further speed boost in the setup process. In the Project Settings<\/b>, under Choose the closest equivalent target platform…<\/b>, choose Mobile\/Tablet<\/b>. However, this is not a good idea to do purely for performance’s sake in desktop projects.
<\/p>\n

Step 10.<\/b> If you begin work in your new project and find it’s running too slowly, your next stop is Settings > Engine Scalability Settings<\/b>. Try dropping the quality to Low<\/b> or Medium<\/b>.
<\/p>\n

Step 11.<\/b> As you develop your project, you can explore finer-grained control over the various quality settings. In the Modes<\/b> pane under Visual Effects<\/b> you’ll find the Post Process Volume<\/b> object, which lets you tweak post effects options.
<\/p>\n

Step 12.<\/b> Once you begin working more in Unreal, you can go to Edit > Project Settings > Rendering<\/b> and find all the available rendering settings listed individually.
