Because GTA IV on PC is notoriously difficult to run on modern hardware (thanks to Games for Windows Live DRM and poor optimization), the most popular Drive links aren't raw installs. They are "fixed" versions. Modders have spent years stripping out the DRM, optimizing the textures for 4K, and re-enabling the Liberty City radio stations that were removed from official sales due to expired licenses.

Liberty City Backup

In the end, Liberty City’s most dangerous weapon wasn’t a rocket launcher or a police chopper. It was a free cloud storage service, a library card, and a man with nothing left to lose.

: Some players use the GTA IV Downgrader to revert to version 1.0.7.0 or 1.0.8.0 for better mod compatibility.
