The population is being deceived on a grand scale. The Source Engine lacks the fancy shadows of Doom 3, and its largest map will barely cover one-sixth of any piece of the jungle Far Cry, but he knows a lot about shaders and good photo textures, giving the picture a rough earthiness of reality.

Faded paint on a car bumper, the glare of dim streetlights on the troubled surface of an underground river, naturalistic garbage in a half-destroyed house - the atmosphere of City No. 17 is woven from such little things, filling the plot vacuum. There are no loud shades here, and the glossy bump mapping, which in other games makes it seem like everything has been doused with sunflower oil, is used strictly for its intended purpose.

Source Engine works fast even on such an antique as GeForce4 MX. Good optimization for many video cards and processors, debugged, like an expensive Swiss watch, program code, and tricks with detailing distant objects work true miracles. You can safely forget about the spectacular special effects available with DirectX 8 and higher, but HL2 all still looks nice.
