I use a 7th gen Pentium dual core processor 3.5 gigahertz with hyper threading, which makes baking lights in compiling shaders a lengthy process but it still works. I have 8GB of ddr4 running at 2400 megahertz. I’m using the NVIDIA GTX 1050 TI with 4GB ddr5 vram. It’s definitely not the best setup in the world but I can run ue4 just fine if you exclude the sometimes long waits for compiling things.
