Awful Performance in Editor 4.18
Creating a fresh third person blueprint project in both 4.17 and 4.18, then using the stat fps command on the editor window, I have 120 frames per second in 4.17, but only 15 in 4.18 with frequent dips and freezes. While working in 4.18 performance will get worse and worse until the editor completely freezes.
Here is the interesting part; If I open a 4.17 project and leave it open , I can open a 4.18 project and not experience the performance issues. However, if the 4.18 project is already open, opening a 4.17 project does not have any effect.

In the dxdiag I noticed that you are using the latest driver by NVIDIA, the 388.31 driver is not on the supported drivers list for the Unreal Engine. Currently the supported driver for the 900 series of NVIDIA GPUs is the 388.00 driver.
I would recommend rolling back to the 388.00 driver and see if you are still encountering the performance problems.
