• Download the latest dxvk (x32 version).
• Extract d3d9.dll into your GTA IV root folder.
• Result: Massive frame rate stability, reduced stuttering, and faster texture streaming. It is night and day.

• Mod Compatibility: The vast library of GTA IV mods—from ENB Series graphics overhauls to ScriptHookDotNet mods (like the iconic LCPD: First Response)—was built for 1.0.7.0. Modern versions break these mods completely.
• Performance: While not perfect, 1.0.7.0 handles modern graphics cards better than the CE. You can force higher draw distances and disable the aggressive "clip streaming" that causes texture pop-in on newer versions.
• No Rockstar Launcher Bloat: The Complete Edition forces you to use the Rockstar Games Launcher, which introduces DRM checks that can lag single-player gameplay. Downgraded 1.0.7.0 can run directly from the .exe, bypassing the launcher.
• Re-enabling Radio & Multiplayer: Downgrading allows you to restore cut radio tracks via mods and, with third-party tools (like GTAConnected), even resurrect LAN-based multiplayer.
