objects cast strange shadows

It seems that objects cast shadows on invisible walls, not on other objects.
Strange... is this normal or is problem?

thanks

Can you provide system specs and perhaps a screenshot or two?

this is my conf:
- 2.6GHz with Hyper-Threading.
- Nvidia 5900xt 128 Mb (overclocked)
- 512 Mb RaM.

the screenshots:

done


I tried the video card with normal clock frequency but it's the same..
maybe It has something to do with these variables:

r_useOptimizedShadows
r_useShadowCulling
r_useTwoSidedStencil
r_useTurboShadow
r_useShadowVertexProgram
r_useShadowProjectedCull

thanks for your help

Make a little html page so that we can actually see the screenies.

done.

-edit- Damnation, I meant to edit, not reply.

Looks normal to me. The "invisible wall" is just the far wall on the other side of the room. If you were another player looking at that scene from another perspective, you'd be able to see it better.

Or maybe I just can't see the image properly against a white background.

in the second image the crate with the chainsaw box on the top seems
to cast a shadow on the stairs, but the shadow seems just a square to
me. maybe I am wrong.
ok thanks

Doom 3 isn't THAT realistic.
