It looks a bit changed, its subtle, but its there. The textures have a bit of a "mold" look. Remember the difference between r_depthbits 32 to 16? something like that.
Is there something to make it exactly the same as before? perhaps something on the nvidia display options is fucking this up.
For instance, notice at the upper wall on the first pic, that is the old AMD. Now look below at the same place, the wall looks whiter. Also the wall looks seems smooth, in the sense of it looking a bit more like r_picmip 4 than 5. Look at the floor. Its just different, and its annoying me. Any way to make it look like on the previous GPU?
