  4. Copy these three files: d3d9.dll, dxgi.dll, and d3d11.dll.
  5. Paste them into your GTA IV installation folder (where GTAIV.exe lives).
  6. Launch the game. The first launch may stutter for 30 seconds while Vulkan shaders compile.

Why Rockstar Never Officially Fixed RMN60

The RMN60 error exists because GTA IV’s PC port was outsourced, and the source code for the renderer was poorly documented. When Rockstar released the "Complete Edition" in 2020, they removed Games for Windows Live (GFWL) but did not rewrite the memory management. As GPUs surpassed 2GB, 4GB, and 8GB, the 2008 code simply overflowed.

The community (through commandline fixes, DXVK, and downgraders) has solved what Rockstar ignored. Share this guide with anyone still struggling—because Liberty City deserves to be played, not crashed.
