My decade old laptop (with 1TB SSD upgrade) is just fine for light UE work, if I wasn’t presently involved in an absolutely massive already commercial project, it has an absolute bare minimum Nvidia Quadro, so I can’t run it with my commercial product, but it does fine with the Retro FPS that I’m also part of.
The commercial product is presently 612GB for my \Unreal folder, and I don’t have any of the source assets. The Retro FPS is closer to around 100GB. of course, size doesn’t really mean much, but it gives you an idea of how much more involved one is than the other.
