Your machine shouldn't have any problems with it and it's strange that you can get that far without any other issues. I would recommend you make sure your drivers are up to date (if they are not already) and install the UE4 prerequisites. You can find them in Cardiac\Engine\Extras\Redist\en-us\UE4PrereqSetup_x64.exe. I used a newly added feature for UE4 called virtual texturing that may be causing issues for some people or may not be entirely stable yet. Unfortunately to remove it I would have to remake every texture in the game and the performance would likely take a heavy hit so it's not something I plan to do at the moment.
