Unfortunately on my Laptoy it crashes before it even shows an opening screen.
LowlevelFatalError [File:Unknown] [Line: 198]
Unreal Engine is exiting due to D3D device being lost. (Error: 0x887A0006 - 'HUNG'
There is an "UE4PrereqSetup.exe" hidden inside the depth of the files, but when I run it it gives me an option to uninstall so I presume it was run automatically and not something that one would have to do manually.
(OK, this is strange, on the third attempt it just runs. So maybe opening said installer did something good...)
(Nonetheless, unfortunately on my Laptoy, the sound is already stuttering the moment I hit the "Start" button, and I didn't even move at all... And this being made in Unreal I can't just open the project and try to make a Linux build for it...)
