This can happen due to number of things such as corrupted drivers or system files, 3rd party apps hooking into or otherwise interfering with the game, etc.

Ensure your system and drivers are up to date and remove/disable applications running at background. Additionally restart Steam and your System as that might solve some issues.

ok, reading in the log, it sez, that it cannot identify the nvidia driver. but it is already the very latest. i just updated.

I am currently having the exact same problem....did you ever get this resolved ?

Are you running the latest Nvidia drivers, @BringItOn?

same here, tried all the usual things, even re-downloading but no luck, not sure if 1440p or high refresh is something to do with problem

hi everyone, i'm still having the same issue with UE4 crash all the time, i tried everything reinstall windows and updating all drivers, deleting the game config file the game still crash, anyone got the solution please, dev's or anyone 😕 ?
