Not true at all.
Crashing is all about the different systems every one of us uses.
There is no vanilla system like there tended to be pre 2000.
When Blizzard was old school they had a department with hundreds of different pc’s with different OS’s and drivers in date and out of date to test playinig D3 on.
This is gone.
They depend on us now to give the data, which does not work as well from home.
Everyone has a different system from the next guy.
This is why fixing the join bug took almost a whole year.
And it still is broken.
After a Windows update (I’m now on 19041.630) I just checked and I crashed at the start of Act IV approaching Tyrael and Imperius in campaign. GTX1060 with 457.09 driver. Looks like there’s a driver update available, so I’ll update and try again.
EDIT: Updated GPU driver to 457.30 and still crashing at the start of Act IV as I get close to Tyrael. Don’t seem to be crashing in Sewers of Caldeum at least.
EDIT2: I seem to be crashing when starting a new game at the beginning of Act 4, but not when I start at the end of Act 3 and kill Azmodan and then progress into Act 4. I’ve crashed all 5 times I start a new game at the beginning of Act 4, and I haven’t crashed the 3 times I start the game at the end of Act 3 and progress through to Act 4.
