I've been having some issues with FF14 and my new Geforce GTX 660. Pretty regularly I get graphic tears and "disco strobe effects" as the game starts drawing multicolored vectors randomly. Shortly after, my computer freezes and requires a hard boot.

Oddly enough, I have less problems with crashes in the open world. Dungeons, on the other hand, are almost certain to crash the game. Sastasha, Thousand Maws, and Hatali are particularly bad for it. Dungeon runs only last about 20 - 30 minutes before it is disco time. The open world is usually good for several hours.

FF14 is the only game I have problems with. All others (Left 4 Dead 2, Shogun 2, etc) run at maximum settings without a hitch.

I have tried Nvidia drivers 326.8, 320.49, and 326.41 without any luck.

I have played with all sorts of settings in the game. My current set up (windowless border, 60fps lock, 1280x, culling on, and standard settings is the most stable. Stable, that is, if you count dungeon crashes as normal.

Does anyone have suggestions?
