shadows 2 was never exactly bug free, i'm not sure i'd even be concerned if what you see as a problem definately didn't happen with other drivers. you do need to be sure stencilbits 8 is set also or something.

There's nothing that I can tell is wrong with shots 4 and 5. They look better in motion though. In shot 1, I don't think the shadows from the armor and rail ammo should be up there high on the wall behind that torch...

If stencil bits is set to 0, shadows 2 will not display.
