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"

Hi 21 builds,

After researching this issue, I found a post that read, "there is an optional update within windows update that enables level 10.0 in dx11. So you can either look for the specific optional update and try installing it (KB2670838), or even better (because there are some prerequisite updates) make sure you install ALL optional updates so your pc is current.

There is also a platform update (KB2670838) from Microsoft that users used to fix this error found here:


Be sure you pick the appropriate Windows (x64 or x86)."

If this does not work, then please post your post dxdiag.
