Pure UI packaging

I have a pure UI project, but running on the integrated graphics card, click UI will delay 1 second trigger, UI animation 1 second 2 frames, is there any solution? For example, how to turn off the running of the engine.

Is there any way to turn off some of the rendering channels that are not needed by the UI? After I changed some of the settings, it was delayed by 1 second and now becomes a delay of 0.6 seconds. But not enough.Computer configuration, only one J1800 CPU, no separate GPU

Your computer absolutely does not meet the minimum requirements to run UE4, that CPU is 6 years old and was on the low end when it was new.
