Ok so I only tested in town as I was getting 60fps outside of town most of the time. With everything maxed and at 1900x1200 I got a 6 FPS boost with these drivers. I'm running 2x gtx 470's on an EVGA MoBo, if it even matters.
However at my normal settings in windowed mode, I really didn't notice much visual improvement.
Either way, as far as XIV is concerned I don't have any graphical issues and this WHQL has the SLI fix already implimented (as did the last 2 Beta drivers like I mentioned previously).
Bottom line, from my short testing... there's no reason for Nvidia owners not to upgrade to this driver as far as XIV is concerned.
