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"

Unreal Engine is exiting due to D3D device being lost.

This is an old bug. I have seen it on the blog but didn't actually meet it. and now it occurred.
alt text

In "Known Issue" it seems been fixed, but I think the issue still exists.
I find something interesting.
My computer is a laptop. When I use AC Adapter, It will never occur. But when I use battery It will occur in 10 seconds.
In my memory, UE4.17 and 4.16 didn't show this error even I use the battery.
Maybe It due to a driver update?
At last, I think this bug needs to be fixed. Because of it, I can not use Unreal Engine with the battery even a minute. And if there is a power failure, I must close the editor immediately or the crash may destroy my project.
Hope you can find out what makes the issue occurred.

Product Version: UE 4.19

The same problem, only I have Radeon integrated with Intel. I do not know what to turn off or on.

Check if there is any battery settings in radeon tool or manager or something.

This Issue seems due to NVidia GeForce Driver.
When I install an older driver(GeForce Notebook 388.43), the crash is disappeared.UE4 works fine with the battery.
But when I reinstall the latest Driver(GeForce Notebook 397.93), the crash appears again.
If anyone has the same issue, rolling back the driver may fix it.
Still, hope NVidia or Epic can look at this issue. People shouldn't always stay with an older driver.

if you are using a laptop.. do the following first.

  1. connect your laptop to charger. open unreal engine and open file menu and hover mouse over it. if it works fine leave it. mostly the crash won't happen.

  2. disconnect your laptop from charger. now again... open unreal engine and open file menu and hover mouse over it. MOSTLY NOW... THE CRASH MAY OCCUR.

IF THE CRASH OCCURS.... DO THE FOLLOWING.

NVIDIA GEFORCE EXPERIENCE -> GAMES -> BATTER BOOST -> DISABLE IT !!!!!!

AFTER DISABLING BATTERY BOOST ON NVIDIA GEFORCE EXPERIENCE.. TRY THE ABOVE 2ND STEP AGAIN. NOW..IT SHOULD BE WORKING FINE MOSTLY.

Perfect !!! My battery of older laptop died when i started creating new unreal projects. Seems like it was because the Battery Boost was unknowngly enabled. Thank you for this post.

Thank you, this worked for me. Dell G3. (Annoying because I had to create an account on NVIDIA first, so that I could disable Battery Boost)
