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"

RenderThread timeout (Intel GPU?)


We regularly receive crash reports from users in which the error line of the CrashContext file reads the following:

 <ErrorMessage>LowLevelFatalError [File:D:\Build\++UE4+Release-4.18+Compile\Sync\Engine\Source\Runtime\RenderCore\Private\RenderingThread.cpp] [Line: 1015] GameThread timed out waiting for RenderThread after 30.00 secs</ErrorMessage>

Looking over the crash context files, the following GPU's are reporting this:

  • Intel(R) HD Graphics 4600

  • Intel(R) HD Graphics

  • AMD Radeon HD 7520G

  • Intel(R) HD Graphics 530

  • Intel(R) HD Graphics 630

The common denominator appears to be that it affects on-board graphics chips. If it interests you, I've got one stack trace from a dmp file that I can share:

I realise that these users are technically running the game on unsupported hardware (I believe at least?) but if there's a bug here that can be patched up, I know they'd appreciate it.

Oh - one last "clue": We've had two users (hardly any though) suggest that they were able to overcome the crash by running the game in a lower resolution. To me it sounds like the issue could be outside the UE4 engine (driver/hardware side), but I'm no expert on that matter.

Thanks and good luck,

Product Version: UE 4.18

intel hd is not a dedicated gpu and therefore is not supported by the engine. you need to be using a dedicated graphics card or at the very least a mobile variant. integrated graphics does not have the performance needed and it also detracts from the available processing power and memory of the system.
