Yeah, I don't mean to say it ISN'T a driver issue, more so then the sentiment that it's not an issue with dragon age itself. There's always the possibility of multiple different things causing crashes that overlap in symptoms.
There's a bunch of people here and on Reddit and such who will immediately comment in threads with "ITS YOUR HARDWARE, MINE DOESNT CRASH" which at best hinders the ability to get meaningful information when cutting through the noise, and at worst wastes a bunch of people's time thinking their hardware is at fault or they are alone dealing with the issue.
It gets annoying to see, just like the above, where someone (not you op) says with full confidence that it absolutely must be a problem with your hardware because software doesn't crash hardware, which is just wildly incorrect, and it does nothing to actually progress the elucidation of the real problem. They also haven't read any of the other threads before posting or they would have seen the full breakdown of what people have attempted and what they've found, none of which points to the actual hardware having an issue.
I don't understand why they even post in the threads, it just muddies the waters.
