campaign looked great to me the only thing that stood out was blocky shadows
theres alot of graphical assets that separate ghost on next gen vs last gen CODs other than the huge rez boost like
much better anisotropic filtering
horizon-based ambient occlusion
higherprecision effects for depth of field, lens flare, and light shafts
displacement mapping and substantial increases in polygon count
use of lighting, tessellation and the dramatic increase in texture quality
tessellated characters, physics-driven particle effects
simulated global illumination,
screenspace reflections on glossy surfaces, more shader effects that more realistically represent various materials when they are illuminated by a dynamic light source
