I've been playing for ages with 1 MSI 1080ti in my system with no dramas at all.

Just added a 2nd 1080ti to my system in SLI and everytime I now try to load game, I get to the menu screen, no problems, the intro video will play, no problems, I click on resume campaign and game starts to load, then just crashes and I end up back on the desktop.

I'm running an i7-7700k processor, 16Gb of ram, on windows 10 64bit.


Any ideas as to why the game would just suddenly start crashing?
