Below are the comparisons between Concept and Game (this could also include
images from screen testing before game release).
This is a comparison between Concept Art and Design and in Game Art and Design,
the comparables used are Aliens v Predator 3 and Aliens: Colonial Marines
and after patched and original and patched and modded in DX10/11 for Aliens: Colonial Marines.
With the new patches for Aliens: Colonial Marines the improvements have been
noticeable, improving both textures and lighting although shadows continue to be
intermittent. Something Aliens v Predator 3 in either DX9/10/11 didn't suffer
from with DX11 having improved lighting and tessellation and DX11.1 features FXAA/MLAA/TXAA
improving textures and lighting further. The increased darkness in Aliens: Colonial Marines modded
versions make it darker then they need to be with a flashlight improving little and there are no
flares available as have appeared in the films Aliens and Alien 3 or either the games Aliens v Predator, Aliens v Predator 2 or Aliens v Predator 3.
Testing and final versions are considered different as fewer items are loaded in under
testing and in some cases include many more sprites (characters) then you will
find in the final version. These shouldn't be considered as final quality of gameplay because they are usually better in quality and resolution.
There would be few improvements in Aliens v Predator 3 as from the offset include DX10/11 options, a problem with Aliens: Colonial Marines but with modded version options improving textures but having an adverse effect with lighting. These are not official as official releases include patches and HD textures.
