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"

Sudden FPS Drop When Loading Sublevel

Hi all,

As I have a relatively large map, I am using level streaming to stream in and out small chunks of my open world map. The actual level streaming works fine, but every time a sublevel streams in or out, the FPS goes from 70 to about 3 for maybe a tenth of a second, and this makes a really noticeable jerk. This means when the player moves around the map, every now and then this jerk happens. I imagine this is related to the sublevel trying to stream really quickly all at once - but I would rather it streams slower and doesn't have such an impact on the FPS. How can I force it to do this?
