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?
I have the same problem. After 3 Minutes the fans crank up and this is annoying…dont know where the setup´s are
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.
