Oh frabjous day. I'm so happy to hear that other people experience the manifold wonders that compose FFXIV crashing. Not. More seriously, my condolences to the rest of you.

I'm of the nvlddmkm.sys reset error variety myself. I've gone through basic fixes (reinstall drivers, clean reinstall, clear registry, etc), and went through lists of other suggested TDR error fixes. Looking like nothing helps though, and the error only occurs in FFXIV. At this point regrettably my best hope is that it gets fixed by the developers, which based on this thread seems unlikely. I suppose I'm not that surprised, I helped alpha test the original game, and well, I'd call it a catastrophe, but that implies there was substance to it in the first place.
