I had this same problem two times today, my spec are little bit lower but yes it crash my app. In your case one Intel9 is not even bad cpu for regular pc (not including Xeon servers) but we don’t know what model of gpu you use. Sometimes gpu’s more than 8gb memory are good cards but it may depends of card workflow, I mean if you have Radeon series card like me from thier webside are some API’s, SDK and tools that optimize work of cards, in this case I choose Vulkan optimization for OpenGL and CL apps like Unreal and 3dsmax. If your have Nvidia cards you should looking for other api’s from nvidia developer side to optimize your work at unreal.
