There should be exactly the toggle that the article asks for given this criticism. I don’t know how likely it is, because it seems like whatever engine they fed this game into just handles lighting very differently. Deus Ex is a great game, but I’m personally of the opinion that it’s quite ugly, and just about anything you do to the graphics are an improvement. The mod that the article compares it to doesn’t look better, just slightly different. In either case, the reason that both look better than the original, and why we pulled out the year 2003, is that the technology in cutting edge graphics didn’t really change until mid-to-late 2004, and the advancements in between were basically just more polygons and better textures, which is all you can reasonably expect in a remaster. More than that is a lot more work and gets you into remake territory.
