Grand Theft Auto IV (GTA 4) is an iconic open-world action-adventure game known for its immersive storyline and thrilling gameplay. However, some players encounter a frustrating bug during the last mission involving a helicopter, hindering their progress in completing the game. If you’re facing issues with the helicopter bug in the final mission of GTA 4, fear not! We’ve compiled a comprehensive guide to help you troubleshoot and resolve this issue, ensuring a smooth and enjoyable gaming experience until the very end.
How to Fix GTA 4 Last Mission Helicopter Bug
The helicopter bug in the final mission of GTA 4 occurs when players encounter difficulties climbing onto the helicopter during a crucial moment of the mission. This bug can manifest in various forms, including Niko Bellic, the protagonist, failing to grab onto the helicopter or experiencing glitches that prevent progression. These issues can be frustrating, especially when attempting to complete the game’s storyline.
1. Use Fraps to Limit FPS
One of the most effective solutions to fix the helicopter bug is to use Fraps, a software tool that can record and monitor game performance, to limit the FPS (frames per second) of the game. High FPS can sometimes cause glitches and inconsistencies in game mechanics, including the helicopter bug. Follow these steps to use Fraps:
- Install Fraps and set it to record at 30 FPS.
- During the final mission, when attempting to climb onto the helicopter, start recording with Fraps.
- Press forward (hold) and tap the spacebar rapidly until Niko successfully climbs into the helicopter.
- After completing the climb, you can turn off Fraps and continue with the rest of the mission.
2. Change CPU Affinity
Another method to address the helicopter bug involves changing the CPU affinity settings of the GTA 4 process. By limiting the game to run on a single CPU core, you may mitigate the issues causing the bug. Follow these steps to change CPU affinity:
- Play the game until you reach the point where you need to jump onto the helicopter.
- Pause the game by pressing the “Escape” key.
- Open the Task Manager by pressing Ctrl + Alt + Del.
- Switch to the “Processes” tab and search for “GTAIV.exe”.
- Right-click on “GTAIV.exe” and choose “Set Affinity”.
- Uncheck all CPU cores except for one, then press “Ok”.
- Return to the game and attempt the helicopter climb again.
