Grand Theft Auto IV is often remembered as one of the most ambitious entries in Rockstar’s legendary series, but also as one of the most technically problematic PC ports of its time. From poor optimization to locked features, the game never truly reached its full potential on modern hardware. That’s where the Fusion Fix mod comes in—essentially transforming GTA 4 into the remaster fans have been waiting for.

Developed by the modding community,  Fusion Fix  directly addresses many of the long-standing issues that plagued the PC version. It introduces proper controller support, widescreen fixes, improved frame pacing, and restores visual features that were either broken or removed in the original release. The result is a far smoother and more polished experience that finally feels worthy of a modern revisit.

What makes Fusion Fix stand out is how it goes beyond just performance tweaks. The mod reworks cutscene behavior to eliminate bugs, corrects the aspect ratio across menus and gameplay, and even fixes texture streaming problems. Combined with higher resolution textures and community-made ENB presets, players can essentially enjoy a remastered version of Liberty City without waiting for Rockstar to deliver one.

Performance-wise, the improvements are striking. Frame rates are far more stable, crashes are reduced, and the game now scales properly with newer GPUs. For those who struggled with GTA 4’s notorious stuttering or input delays, this mod is a game-changer.

While Rockstar has yet to release an official remaster of GTA 4, Fusion Fix proves what’s possible when passionate fans step in. For players nostalgic for Niko Bellic’s journey—or newcomers curious about one of the most story-driven entries in the series—this is easily the best way to experience it today.
