Grand Theft Auto IV, released in 2008, is considered a masterpiece of storytelling and open-world design. However, its PC port is notoriously problematic. Over the years, Rockstar released several patches. The final "Complete Edition" (version 1.2.0.xx+), which replaced Games for Windows – LIVE (GFWL) with the Rockstar Games Launcher, broke many mods, reduced graphical options, and introduced new performance stutters for a significant portion of the player base.
The Complete Edition removed 20+ songs (like "I'm Not Your Toy" by La Roux). Download the "GTA IV Radio Restoration Pack." It injects the missing audio files into the audio\sfx folder without breaking legality (it uses files from the original disc or legitimate sources). downgrade gta iv to 1070
