I haven’t touched ue4 in quite some time so I don’t know whether it’s because of the latest update or some other variable. A year back there was absolutely no delay with this computer.
My specs aren’t to bad though I’m using a cloud pc:
CPU: Intel Xeon E5-2678, 2.5 GHZ, 8 cores
GPU: GTX 1080
Ram: 8gb
SSD: yes
