Crash with packaged build

I’m developing a game, and I wanted to try it out with a friend, but he has pretty low end PC, and he keeps crashing randomly, with these logs:
[File:D:\Build++UE4+Release-4.12+Compile\Sync\Engine\Source\Runtime\RenderCore\Private\RenderingThread.cpp] [Line: 717]
Rendering thread exception:
Fatal error: [File:D:\Build++UE4+Release-4.12+Compile\Sync\Engine\Source\Runtime\Windows\D3D11RHI\Private\D3D11Util.cpp] [Line: 180]
Unreal Engine is exiting due to D3D device being lost. D3D device was not available to assertain DXGI cause.

Haven’t found much, but I’m guessing that he does not meet the requirements. Is there any way to lower the requirements? Turning off features, or so.

My game does not use that much of the rendering capacity, I have only one custom shader( which is a simple toon shader ), and some low poly models, with low resolution textures (around 256x256).

Any ideas what could I do to be able to run on his computer?

Hey honya15,

So the issue here is that at some point the graphics card is becoming disconnected. What I’d recommend is that your friend ensure that their graphics card drivers are fully up-to-date. If after updating the drivers, your friend is still experiencing issues, it is most likely an issue with the hardware itself and might mean that they need to upgrade in order to run the editor.

Let me know if you have any further questions.

Have a great day

So there is nothing we can do?
Unfortunately, newer drivers are not compatible with his graphics card, so upgrading is not an option.

Thanks anyway ;(

I just wanted to add that I had the same problem with a map a made. When I pressed play, it took like 10 seconds to load and then it crash. I find out that my SkyLight component had the resolution set to 1024, compared to 128 set as default. So now that it’s fixed, the game loads instantly.

I hope it can help!
