Multiple Nvidia cards, pretty recent drivers, Win7.
I prefer playing with the cloth map only, which I either enable or by setting the cloth map threshold to 100 (or 0, whichever).
Manually save a game, or even just pull up the menu, when I close the menu (closing or by saving), the world is 3d again and no objects appear on the map anywhere. The only way to fix it is by reloading the save.
