I just got the Windows 10 creator update and now my Unreal Engine installations is broken. All UI interactions in UE 4.13 and 4.15 are now extremly slow. If I want to open a context menu in blueprint oder a menu from the dropdown menu bar, it takes ~40 seconds to open it. So it’s nearly impossible to work with.
This issue isn’t just on Unreal its across all apps on my machine…
Basically you need to remove context menus (for NVIDIA and in my case Intel as well)
