I'm actually surprised that the 314.22 driver for Nvidia is still the best one as far as mitigating crashes... Then again, it was one of the last drivers specifically released for FFXIV version 1.0.

I actually switched to the newest "Game Ready" drivers they've released (note that they've tuned it specifically for Battlefield 4) and it seems to work better than 314.22 for me (as far as errors go), with a slight drop in fps.

*disclaimer*

Please note that I have never experienced the R6025 run time error myself and have been perfectly stable since the official release. I was unable to play most of the time during the Alpha/Beta phases due to errors that most everyone else experienced.
