Warhammer, and Warhammer 2, have both long randomly hard-crashed my PC. Total lock up, I have to hard-boot by forcing the power off.
It happened less frequently with Attila and Rome 2.
But ONLY this series has crashed my PC like this in the last 12 years. It's just Total War. It's a loooong running thing that seems to be most prevalent in WH2.
I have no idea what happens, as since it makes me hard boot there's no errors spit out or even logs generated.
I do suspect it has to do with AMD graphics cards from the DX11 era. That's about all the info I can give
You guys haven't fixed it across 4 games though, so I doubt you ever will.
It's just been particularly prevalent in this last Hunter Beta, especially when playing Bretonnia for whatever reason.
It almost always happens when:
A) Starting a turn (just after end turn).
Loading back into the game after a battle.
C) Saving the game.
