Hello guys! I’m using Unreal Engine 4.12 in:
Windows 10 64bit, Intel(R) HD Graphics Family, 6G RAM, 500G HDD, but it’s too slow and is stopping when i’m working . What is the problem ? 
I’m not sure your integrated graphics card is up to the job I’m afraid.
I think the minimum requirements are:
NVIDIA GeForce 470 GTX or AMD Radeon 6870 HD series card or higher.
Wow! My processot is intel core i5 … I prefere Unity :))) .
