Unreal engine doesn't run better or worse if it's a desktop or laptop. It's simply a program. It's your laptop that sucks and perhaps you should get something that can actually work as a computer. Like Gcbuilder said Microsoft or Sony must approve games and all updates going to consoles. Also, it's a completely different software system so DigitalFur would have to code the game from scratch to make it even work and he's be working on this game by themselves. He's already said no to a mobile port meaning it's not going to a console.
i didnt say "Microsoft or Sony must approve games and all updates going to consoles" i say "i dont think" sure my worlds are shit and doesn't make sense but anyway, i get it DigitalFurBelow aka dev should REALLY care about lower end laptop that cant run the game with high graphic, so i think what DigitalFurBelow should do is to put the graphic on a very lowest setting he can and that should maybe fix the crash for lower end laptop
