SWTC is a graphical modifications aimed at improving the image as a whole, completely new weather, more than 120 texture of the sky. It also bring new sounds of nature and ambient. The mod uses a dynamic weather system to make it unpredictable. I worked very hard on the graphics part of the modification, such as static light now has HDR effect. Full dynamic lighting uses SSAO,HDR and anti-aliasing. Completely new shaders based on the Stalker builds 2215 and 2232. This does not include new locations, new story or new gameplay innovations.
