I'm using an Nvidia GeForce 250 GTS. It is not in your unsupported card list. Yet, every time I play this game the video drivers are constantly crashing. Considering I play other graphically intensive games near the highest of settings and have no crash issues and throw in the fact that I'm not the only one that is experiencing this, I'm extremely certain that it is YOUR problem.
This has been happening since the game launched. It has killed me several times due to inconvenient lock ups where it would crash, then come back in about 6-8 seconds later only to crash immediately again. I refuse to even attempt to level my hardcore character for this very reason.
Now, as of the 1.0.4 patch, it is happening in such frequent succession that it's outright CRASHING my game, causing me to lose all my valor stacks (by the way, no grace period added in yet for people that disconnect from a game to keep their stacks? Nice job Blizzard.)
So, does Blizz just not care?
