Whenever I pause my game using console command “pause” and then put my windows 10 computer to sleep, the game has crashed upon resuming windows after a while with the error:
Fatal error: [File:D:\Build++UE4+Release-4.15+Compile\Sync\Engine\Source\Runtime\RenderCore\Private\RenderingThread.cpp] [Line: 932]
[2017.11.02-08.08.55:581][655]LogWindows:Error: GameThread timed out waiting for RenderThread after 2033.93 secs
Unfortunately the project I’m experiencing the error in is several GB’s in size.
Though I think an empty project should trigger the same error. Probably the elapsed time, triggering the timeout, is measured by the windows clock. So that it thinks it’s been waiting on the render-thread for all this time, but actually windows was just in standby.
It’s rather strange that render timeouts can occur while being paused, since it’s not rendering anything.
I was able to replicate the issue. I have logged a JIRA ticket with the developers for them to address this. You can access UE-52315 at anytime to check the status of the bug.
