By following these instructions, you’ll learn how to adjust settings, optimize your system, and ensure that the game runs smoothly on your PC. Whether you’re a seasoned gamer or a novice, these steps are designed to be clear and actionable, leading you toward a stable gaming experience.

Before you begin, ensure that you have the following ready:

Step 1: Run Ubisoft Connect and Steam as Administrator

To start, ensure that both Ubisoft Connect and Steam are running with administrator privileges. This can resolve various permission issues that might cause crashes.

1. Type “Ubisoft Connect” in the Windows search bar.
2. Right-click on the application and select Run as administrator.
3. Repeat the process for Steam.

Step 2: Disable G-Sync in NVIDIA Control Panel

Disabling G-Sync may help stabilize the game performance. Here’s how to do it:

Step 3: Change to Windowed Mode in the Configuration File

Switching to windowed mode can also prevent crashes. Follow these steps:
