I’ve tried launching from both unreal launcher and directly run UE4Editor.exe. However, The system immediately crashes. I am using windows 7 64bit, Graph card: ATI FireGL V5600.
Can ATI FireGL V5600 meet the min. Spec. for unreal engine 4?
Thanks God! I’ve solved the problem, which was caused by out of date graphic card, ATI FireGL V5600. ATI FireGL V5600 only supports DirectX 10. It doesn’t support DirectX 11. After I replaced a new graphic card, which supports DirectX 11, the problem solved.
