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"

Frame Rate Drop When Releasing Right Mouse Button

I've actually noticed this throughout previous versions. When UE4 is asked to render a lot on screen, doesn't seem to matter what, the frame rate drops by sometimes, a whopping 20 frames. The drop only lasts about millisecond, but sometimes (on rare occurrences) the editor will hang for slightly longer than a second. I've tesed this in both my own levels and the examples provided by epic (those with a lot on screen I:E particle effects)

I:E I'll be running a tilled landscape at a solid 38 FPS then when I release the Right mouse button and the frame drops, just quick enough for the fps reader to read it.

This isn't a big bug, and honestly it doesn't bother me to much. But just thought you guys would want to know.

Product Version: UE 4.13

Hi Haflurgaflur,

Unfortunately, I have not been able to reproduce this on my end with the steps provided.

  • Does this occur in a clean, blank project with no additional content or is it limited to one project?

  • What steps can I take to reproduce this on my end?

  • What specific demos can I use to reproduce this if it does not occur in a clean project?
