Permanent crashes. Use Windows 10 64bit.
Error message:

assertion failed: [File:D:/Build/++UE4/Sync/Engine/Source/Runtime/Windows/D3D11RHI/Private/D3D11Util.cpp] [Line: 198] Unreal Engine is exiting due to D3D device being lost. (Error: 0x887A0005 - ‘REMOVED’)

What can I do? thanks for your help

You have luck. In my case the hole system crashes. No error messages, no bluescreen reports or so.
