I got a Acer predator Helios 500 is that okay
Unreal Engine should run fine on that laptop.
I need to let you know when i went to website to try to download it did a speed test then nothing happened after i try again it kept on doing same thing.
Also how many gigabytes is the download is it colossal.
For just the core components, you are looking at around 10GB. Editor symbols and mobile platform tools can add 5-10GB. You can also compile the engine from source code (~1Gb download), but the total size on disk will be similar to if you installed it from Epic Games Launcher.
