[SOLVED] It appears that DirectX 12 needs to be used but isn’t being launched/used/whatever when the UE editor is launched. My solution was to find the shortcut that launches the *.exe and add *-DX12 *to the target properties.
I navigated to the exe’s shortcut by opening the start menu, finding the button, right clicking on it and selecting More> Open File Location. This took me to the folder where the shortcut is located. Optionally you might be able to find it in your Programs folder located in the Start Menu directory. Mine was located here:
- …Users > me > AppData > Roaming > Microsoft > Windows > Start Menu > Programs > UE4.18.0
Right click on this shortcut > General > Target
Inside this Target cell is the location of the targeted exe. All I did was add a space then *-DX12 *to the end of it. That’s all. I now maintain a healthy fps no matter what part of the UI the mouse hovers over.

I’m having the same issue. The FPS is awesome until I hover over the UI. That’s when it drops to 1.8fps. Has anyone found a reason why this is happening? I’m wondering if there’s a pref setting being missed or something. It’s happening on both versions installed on my machine:
- UE4.18.0
- UE4.14.3
Workstation specs:
- Windows 10 64-bit
- Intel i7-6950x @ 3GHz
- 128GB DDR4 SDRAM
- Nvidia Titan-X (Pascal)
Thanks in advance.
