Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Massive framerate drop on GUI interaction

Hi,

I just got into UE4 and I'm having a bit of trouble with the performance of the editor. I'm running the engine on a completely new laptop (MSI GE62 - dxdiag below). Bought it only two days ago, so it's a pretty clean setup too. The framerate is at a constant 60fps whenever I navigate in the viewport. However, if I interact with the editor's GUI (and by "interact" I mean, hovering the mouse over a button, or any other highlighting GUI element) the framerate drops down to roughly 9fps.

In fact the problem is the same as the one posted here: https://answers.unrealengine.com/questions/265199/extreme-framerate-drop-video-included-in-post.html However unresolved for 4.10, or at least this system.

Found the problem. Already kinda suspected it. It's a conflict with some of the laptop's pre-installed software (that's why you should format newly bought hardware I guess). More precisely it's a conflict with:

Nahimic for MSI (v1.2.2 )

which is actually a program for sound managment.

However it seems to run a screen overlay that shows notifications whenever you plug in a headset or microphone ("External Audio Device detected - Optimize here" and stuff like that).

To me it seems that this particular feature is in conflict with the UE4's GUI. Anyway, to solve the problem:

  • Close Nahimic

  • Restart Unreal Engine

And that's it. For others experiencing a similar problem I recommend closing any software that shows similar notifications.
