Per title; whenever entering OG (most usually from New Gridania), the game frequently (not always!) will flicker then hang until I force it to close. Behavior frequently repeats when loading again after re-launching the game.

Have not experienced this when entering any other zone thus far. Game plays smoothly otherwise.

Video card is a GTX295 using the 326.80 drivers (have been the most stable for the older card), but I'm not getting any driver related issues that I can discern.
