Are you sure the videos and screenshots you seen were not of the PC version, I know they have better textures.
My textures look the same as yours, just count yourself lucky you don't have the extreme version of the texture glitch. Just uninstall your game and clear the cache, that should help for the time being if it is the texture glitch we hear so much about, then reinstall later when the patch is released.
Once again, hope I helped.
