At this moment I’m running on an MSI Apache GE70 laptop, with 12 gigs of ram, an i74700HQ, and a GTX860M graphics card. So far Unreal runs beautifully on my machine, I’ve barely had a single issue with it. Granted I haven’t done anything too fancy and don’t really plan on it, I’m mostly here for Paper 2d. The hardest I’ve pushed it was the particle effects tutorial series, and that worked without a hitch. If you’re going for a relatively cheap laptop to learn Unreal and do some basic stuff with it, this spec and up should work pretty well. Be warned though, high performance laptops are loud, expensive, and get really hot. You’ll get more bang for your buck building yourself a desktop if you can, I didn’t because I don’t have a space to put one.
