Fallout 3 temporary VATS FPS fix

[Cryptex]

I don't if anyone else is having this problem, but whenever I use VATS in Fallout 3, my FPS drops to screeching 2-3 range, and continues even when I leave VATS. I've found that if you hit your escape button then ALT-TAB out, it returns your FPS to what it originally was until you use VATS again. Hope this helps and is fixed in the next patch
