Ok, thanks. And is this worth having enabled? Performance killer?

[skouras]

you will see no big deal in the graphics
almost none
but you will see a big difference in performance
i live it OFF as i have everything else on highest

It is a shading algorithm and it is basically there to provide depth to your textures. In other words, it is a resource hog and you won't see much difference unless you're close up.

so if we tick it in the menu..is it enabled or off?

If you check the box it is turned on and you take a big performance hit.
