The graphics mod turns GTA IV into a photo-realistic high-end graphics spectacle with stunning light effects, depth of field, motion blur, lens flare and reflection effects as well as added weather conditions.
According to the developer, the mod is compatible with GTA IV versions 220.127.116.11 to 18.104.22.168. The download is about 3.7 MB and almost certainly will affect the gameplay experience in ways other than pretty effects. It appears that the mod will drop the fps performance by up to 20 percent and the developer noted that especially GeForce 400-, 500-, 200- and 8800-series cards tend to overheat when running the mod. To avoid any damage, Keilany provides a special dll file for those cards. Users who are installing the mod are advised to read the attached readme file.
Keilany had announced previously that there will be no more updates for GTA IV. There is currently a poll on his Facebook page that asks users which game should be modded next. At this time, it appears that there is a strong preference for Skyrim, followed by Minecraft and GTA V.
