Hello, this has been happening not only to Warhammer 2, but damn near every single Total War game I've tried to play as of late. I would start the game up and within 10-30 minutes, depending on whether or not I started a battle right after starting the game, it goes immediately to desktop, sometimes it freezes for a few seconds before, sometimes it's a straight CTD.
I've tried everything I could find online, maybe someone has a solution that might do the trick.
To narrow it down here's what I've tried so far:
Reinstalled the game
Deleted and renewed the appdata folders
Run game/steam/epic games store as administrator
Turned on VSynch and capped frame rate
Made sure my graphics drivers were updated
Rolled back my graphics drivers
Completely deleted and reinstalled steam and epic
Ran compatibility modes
Lowered graphical settings
That's about all I can think of. What sucks is that I had this PC built as a Total War machine. Here's my specs and crash report. I really hope someone here can find a solution for this problem.
