what processor do i need to run this program?


here is what is said in the FAQ:

some more info can be found here or you if you google “UE4 cpu requirements” you should find quite a lot of info on the subject.

hope that helps:)

You need atleast 64-bit CPU i don’t think there any other hard requirments for CPU, other then that it will be just matter of speed, UE4 is for free so go ahead and test how it runs on your machine
