Note on Versioning: Many users search for "ICEnhancer 4.0" specifically because version 3.0 was buggy, and version 2.1 was too performance-heavy. Version 4.0 struck the perfect balance between visual fidelity and frame rate.

| Problem | Likely Cause | Solution | |---------|--------------|----------| | Game crashes on startup | Wrong ENB d3d9.dll version | Replace with ENB v0.163 wrapper. | | Orange/overexposed sky | Missing or corrupt timecyc.dat | Copy timecyc.dat from mod to pc/data. | | No reflections on cars | Incorrect shader folder | Ensure common/shaders/win32_30 is untouched (reinstall game shaders if needed). | | FPS below 15 | SSAO and DoF too high | In enbseries.ini, set EnableAmbientOcclusion=false and EnableDepthOfField=false. | | Water is pure white | DX10 renderer conflict | Set ForceAntialiasing=false in iceconfig.ini. |

Before hitting that download button, it’s crucial to understand what ICEnhancer (ICE) actually is. Created by modder "Ice La Glace," this mod is not a simple texture pack. It is a deep, complex modification that rewrites GTA IV’s timecycle, shaders, reflections, lighting, and color correction.
