It's late to be making this thread, but I've finally had enough of this issue. I've never had any issue with DH until patch 1.05, and since then, my games inevitably end up having to be ditched because they start causing constant blue screens. Sometimes it starts happening as early as the 1930s, but most of the time it starts in the mid 1940s. They never happen only at a specific date, but they tend to come at around the same time during a game. Initially I suspected that this was caused by my cpu overclock, but at this point I have to discard this possibility. I'm overclocking to 4500mhz, and with my current voltage setting I'm able to pass a stress test without errors and play any other game without any BSOD. As a test, I tried lowering the clock speed to 4200mhz while keeping the same voltage, and the result was that DH still causes blue screens.
