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 Editor Keeps lagging, freezing and crashing

Hello, my unreal has been lagging ridiculously for about 3 months, never had a problem with it before until now. My first conclusion was it being due to a nvidia driver update, ive been in touch with them and they have managed to solve a lot of the problems. However it still crashes every 2-3 minutes, and when I try simulate the game its experiencing lots of lag too.

My specs are not the issue, its a relatively new computer with way over the recommended specs, and I have being trying to solve this for ages now, its really grinding my nerves I am completely clueless.

Can someone please help.

Loosing faith

1 answer: sort voted first

OK lets try to run through some things: first some possible symtoms that cause lag:

  1. game tick

  2. draw call (includes lod changing, item spawning)

  3. and more (alot more)

How are your world settings - (one way is to) editor -> toolbar(the thing you use to build)-> settings->engine scalability settings->(what is there?) now if you change scalability settings then you might have to restart the editor (has i have done before)

back to game tick, what's running

  1. BPs

  2. c++ tick

  3. particals

  4. again more

now I run on both an weak laptop and hefty desktop (both extremes) and don't have many issues with the editor. I would scan through your project and engine settings, check out the plugins and search for things related to rendering and learn about them.
