I study this lecture on an old server because my laptop is much older than the server. Now, I envy your high frame rate. I remember that I open Unreal for the first time. It tells me that I need a GPU; otherwise, the Unreal will not run on my server. So, I decided to trick it. I buy a secondhand GTX 730 graphics card, and the track succeeds. Until now, I am aware of the differences.
But, there are a lot of CUPs on my server. It is possible to tell Unreal to use these deadly idle CPUs.
