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"

Unreal 4 editor extremely slow and memory heavy for a particular project

I followed and completed this tutorial:


I then decided to redo it in C++. I'm about half way through, and I've noticed the editor is unbearably slow for this particular project. The original( blueprint ) version I made uses about 1gb of ram, while the C++ version now uses around 2gb. It takes a long time to load maps( about 2-3 minutes compared to the 30 seconds maximum the other project would take. )

Starting the game is slow, compiling is slower than usual, and nearly every other app on my computer is unusable with this project open. I don't believe this has to do with the project being C++ opposed to blueprints, because other C++ projects and tutorials I've opened have not been this resource heavy.

Am I doing something obvious? Is the project broken? I have 4 C++ and blueprint files in my project at the moment.

I have a few questions that can help narrow down this issue:

  • Does this only occur in this particular project?

  • Could you provide your dxdiag?

  • What version of the editor are you using?

Thank you.

Reposting Bonnnnnn's answer, as it got deleted.

Hey, Sean. This question is pretty old. It turns out I was trying to create an abstract component in the constructor of an actor. Removing this fixed the problem. However, this probably isn't the intended behaviour for trying to create an abstract component(right?). This was also a few versions ago(4.3 I think?)
