The game seem to crash to desktop after the save game warning. I don't even get to a menu or main screen after the copyright blurb and epilepsy warning. Have tried verifying files and my Nvidia GPU drivers are up to date. I'm running a dual core Windows 10 setup. Mobo has inbuilt AMD GPU but that's disabled.

Anyone have any ideas?

Edit:

Changed my resolution from my monitor default of 1600x900 to 1280x720 and got the following UE4 error. If it's any help.
