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"

Do you have to have Direct X 11 support for Unreal Engine to work?

My computer doesn't support dx11 and I'm getting a crash when running it. Does Unreal Engine 4 require Direct X 11 support? Is there any way to change it to 9 or 10 through config files?

You need at least DirectX 10 GPU. Though I don't recommend for working anything that do not support DX11 and is slower than Radeon 7850.

Thank you!!! But now, I need a way to set it to dx10 through the config files, since the editor won't run. Can you please help me?

Add this to command line -d3d10.

I can't say for 100% it will work in new build as I don't have access to it yet. But it is worth a try.
