Add me to the list. I had been getting this for maybe a week and none of the proposed setting changes or such fixed it. I initially crashed in FATEs and the Void Ark, though over time I crashed twice in private rooms and several times in dungeons (including Pharos Sirius - Hard). Most times were DirectX errors, though twice my system crashed outright, once with a horrific buzzing noise. This is on Win 10, NVidia 560Ti. This occurred with drivers 359.06 and 361.43. A couple days I uninstalled 361.43 and reinstalled the last one I used, 355.98. I've run that for several days now and so far, knock on wood, no crashes. The problem is, I missed a number of drivers between 355.98 and 359.06, four to be exact, so if it is a driver issue, I have no idea which driver actually broke it.

Hope this helps.
