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"

Game starts low fps, toggle stat unit and performance jumps to expected

This is the weirdest thing. In editor without the game running I have about 110-120 fps with drops to 90. If i hit simulate the game runs around expected at 70-80 fps, but my target is min 90 fps. If I do VR preview the game starts at about 30 fps and will jump to like 45-55 fps at times. That didn't seem right since in 4.17 the game runs at a smooth 80-90. In VR preview I opened the command lined and called stat unit and the fps jumped up to the expected 80-90 fps. WTF? This is not a misreporting of numbers because there is a visible performance increase while playing the game. I don't understand what it is that could be causing this. Any ideas?
