Since the past update/last two updates, the editor’s ui has started to lag a lot, to the point of me not even being able to use it. The strange part is, the viewport/game part of the editor runs fine.
For example, if I hover my mouse over the viewport I get around 120fps, if I hover my mouse over the editors ui I get about 10-15fps.
System Specs:
Windows 7 64bit
8GB ram
GTX 770 with the latest drivers
Intel-i5 2500k
Here is a video of the bug(?)
Edit; It seems to only happen on things that have a pop-up tooltip.
Just wanted to pop in and say that this resolved a similar issue for me on an MSI ghost pro, some of their software (possibly msi truecolor) was causing the UI lag and exiting the app in the taskbar (and disabling it on startup) worked for me.
there is also another thread in which a user demonstrates how to disable apps on startup, may be useful for some folks!
I had the same issue here with horrible editor performance in Unreal 4.11, since I’d recently updated to the latest EVGA Precision X version and the problems started around the same time, I tried uninstalling it and performance returned back to normal
Weirdly enough, going back to an older edition of EVGA Precision causes no issue with the editor, so it must be something in the later iterations that is misbehaving.
