The final version of Grand Theft Auto 4 graphics mod iCEnhancer has been released.
iCEnhancer 2.1 will be the last iteration of the mod, which bestows a vastly enhanced version of the game's graphical tech.
The mod, created by 21-year-old French coder Haysam Keilany, is available to download for free from iCELaGlacE.com.
You'll need to patch a retail version of GTA4 to the 22.214.171.124 build, download the quick tool Xliveless to replace a .dll file in the GTA4 directory, then finally download iCEnhancer 2.1. NeoGAF has more detailed instructions.
Keilany is now working on a similar mod for Minecraft, and has also experimented with Skyrim.
