Grand Theft Auto IV (Also known as GTA IV) is an open world action-adventure game published by Rockstar Games. Two pieces of DLC has been published so far, "The Lost and Damned" and "The Ballad of Gay Tony".

The game was written primarily for consoles and the PC port is not of a high quality. However, for those who can get it running, there are many mods availible, some of which are spectacular.

ATI Rain Effects Glitch

There is a problem with ATI 69xx (6950, 6970, 6990) cards and drivers at the moment. (And there has been for some time.) The rain shader in GTA IV causes spontaneous red, green, sometimes white starbursts while it is raining. Don't worry! These aren't really artifacts, but a shader bug.

There is a quick workaround. It involves disabling the lighting shader on rain.

  • Open your GTA folder (Usually C:\Program Files (x86)\Steam\steamapps\common\Grand Theft Auto IV\GTA IV)
  • Navigate to common\data\visualSettings.dat and open it with your favorite text editing software.
  • Scroll down to line 20 or so under "#Values for rain GPU particle effect" and change "rain.UseLitShader 1.0" to "rain.UseLitShader 0"
  • Play your game!
