I am using an i5 3230m and unreal only uses 25% of it. No other processes are using it much at all, so there is room. If it only used 50% I would assume it was only using the first core, but not even 50, just 25. Any ideas?
-make sure that you run your pc with the “high performance” energy settings
-in your task manager do a right click on the UE4 - set priority - high/higher than normal/…
-as long as it’s not lagging, be happy that the UE4 just uses 25%
Wait till you begin baking large lightmaps
It only uses what it needs, once you begin building lighting then it should use more.

2 cores, 4 threads - maybe right click on your graph in your performance monitor and switch to the logical view.
p.s if you want unreal to use 99%, build a dedicated server or android client - press F to pay respects to your CPU
p.p.s also in the editor settings there is a “use less cpu if in background” setting in miscellaneous - maybe uncheck that as technically if you are using your task manager, its in the background
