I have seen multiple threads about how Unreal has unstable high CPU bursts when using the engine. Will this ever be fixed? My fans are rapidly going and my CPU skyrockets when I open the program. Will this ever be fixed?

Searching around for an answer, I found the suggestion to user `t.maxfps 60` in the UE4 console. Open it with ~, set that variable, and watch it limit the CPU. You can set it to a lower value if necessary.
