How can you run the game with no specular? Of course it's going to look worse! Not to mention, the screen resolution in the picture is very low. What quality setting were you running in? Low or Medium?
Far Cry is not a good game to compare to Doom 3. It's only even comparable if you have a DirectX 9 video card, which many people don't, and even then it's hard to say. The engines are far too different to truly compare. Visually, however, Far Cry is a little less impressive, in my opinion.
Just because you don't have fast enough hardware to run the game on high settings doesn't mean no one else can. This post is very misleading, and it seems deliberate. Hence - trolls.
