GTA Vice City is a classic in the gaming industry and holds a special place in the hearts of many players. Playing this game in the year 2024 brings back feelings of nostalgia for fans.

However, many players have complained about one problem where the mouse stops working in the game and this causes massive gaming disruptions.

In this article, we’ll explain how to fix the GTA Vice City mouse issues easily.

Here’s what we will cover:

Run Vice City on compatibility mode

The compatibility mode is a feature in Windows to seamlessly run some of the older software that may not run in the latest versions like Windows 10 and 11.

Step 1: Right-click on the Vice City game file ‘gta-vc.exe’ and then click on Properties. The screenshot below is for some other software. However, the steps remain the same.

Step 2: Next, click on Compatibility and then check mark the box for Run the program in compatibility mode for, and then select the Windows version.

Change the processor affinity

This fix is given on the official Rockstar support page. According to the support answer, if the player is seeing any mouse-related disruption in Vice City, it could be because the processor affinity of the game is set to default to all processors.

So, the player should set it to only one CPU processor core. Here’s how to do this:

  • Start GTA Vice City on your computer and then minimise it. Next, open the task manager and then find the ‘gta-vc.exe’ process.
  • Now, right-click on the process and then click on Go to details.
  • Again, right-click on the same process that we have seen in the first step, and click on Set affinity.
  • Finally, uncheck all boxes except the one for CPU 0.

Updating the mouse driver

Step 1: Right-click on the Start menu and then click on Device Manager.

Step 2: Expand the Mice and other pointing devices option.

Step 3: Right-click on the mouse driver and then click on Update driver.

Step 4: Click on Search automatically for drivers.
