Hey
Thanks for providing me with your dxdiag .
After reviewing your dxdiag from your computer, it looks as if your computer is a bit dated. The suggested system requirements for UE4 is having Windows 7 64-bit with at least 8GB RAM, along with a quad-core processor and a DX11 compatible graphics card.
Your computer has a dual core processor, with 1 GB RAM and a graphics card that only supports up to DX9. So looking at these computer specifications, I can tell that your computer is not able to handle UE4. You would at the very least need to update your graphics card and ram, but more than likely you’ll need to update your processor as well since it’s only a dual core.
If you’d like to see what computer specs others are running within the community, check out this [forum thread][1].
Cheers!
