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"

Performance issues with occlusion culling

Hello all,

I'm having a little performance issue with an scene in a project. I think I have ruled out some factors by toggling them while running the scene but there was almost no change in fps, and then I ruled the profiling tool, and while reviewing it I found that something called "Occlusion Cull" was taking a lot of time. Here is a session frontend capture showing the issue:

Does anyone know what could be causing this, or maybe some suggestions on where to look for causes?

Something called SlateDrawWindowsCommand is causing slowdowns as well, perhaps they are related? The time between these two events combined accounts for about 80% of the total frame time.

I have same problem on Intel HD 4600 family, only here SlateDrawWindowsCommand takes whopping 70ms. Even on empty scene. I'm developing an app for industry-pcs, therefor he low graphic specs.
