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"

Can I prevent UE from using the Radeon GPU?

On our Dell OptiPlex 7440 and 7450 AIOs, with dual Intel and Radeon graphics, the Unreal Engine editor is too unstable to use. Disabling the AMD Radeon graphics card resolves the problem, but we don't want to do this, since we run other software that would suffer as a result. I've tried various different driver versions with no success.

Configuring the switchable graphics also doesn't help; I believe Unreal is choosing the GPU itself.

Is there any way to tell Unreal that it should use only the onboard graphics? Or to blacklist particular GPUs?

Product Version: UE 4.21

to use unreal you have to have a dedicated gpu, it wont run on integrated graphics. even if it did you wouldnt get good results since integrated graphics just dont have the same kind of power as a dedicated gpu. i base this opinion on the many threads of people attempting to use integrated graphics who get errors such as level 5 graphics card needed and such. also based on the recommended spec provided by epic linked below.

Integrated graphics is far more capable than it used to be, and these are relatively new machines. I don't believe it will be a problem. (In particular, "feature level 5" appears to just mean DirectX 11 or better support, and the Intel GPUs support DirectX 12.)
