Hi,
So it started around 3 days ago. I've been playing since launch but I hadn't had much time to play it in the last 2 weeks. In that time I would play maybe an hour a night.
I had hoped Patch 3 would resolve the issue but it has happened twice since. Usually I can play a full mission, then maybe a short while after that I'll see a crash. I've also run through your suggested ideas above.
I've also done a clean reinstall of the latest Nvidia driver, repaired the game file and uninstalled and then reinstalled the whole game.
When I started up the game again after reinstalled it, it didn't go through lengthy shader compiling like the first time, just a quick shader verification.
