Why does GTA 4 lag on my PC?

How Do I Fix the Lag on a GTA 4 PC?

• Answer:

  Lag time can make playing even the most enjoyable games a horrible experience. It frustrates not only the player, but also his online teammates or competitors. Lag issues often are caused by slow online connections. Offline problems can be caused by programming bugs and improper drivers. "Grand Theft Auto 4," or GTA 4, has been known to have a series of lag issues with multiple fixes. Some of these issues have been addressed by Rock Star Games in the form of patches. Difficulty: Moderately Easy Instructions Ensure the game is closed and not running in the background. Open the computer's control panel. Select the device manager. Right-click on the graphics card. Select "Search for updates." Install any updates. Log on to the Rock Star Games website. Under the help and support section is a link for GTA 4 support. Click on and download any patches offered. When the downloads are complete, install the updates. Open up the Start menu. Type "services" into the search bar. In the new search field, search for "Superfetch." Double-click on the resulting pop-up. A menu will appear. Disable Superfetch. Open the GTA 4 folder in Program Files. Locate the "LaunchGTAIV" icon. Right-click and create a shortcut on the desktop. Right-click on the shortcut. Open the properties menu. Add "-novblank" after "\Rockstar Games\Grand Theft Auto IV\LaunchGTAIV.exe." This addition will disable V-Sync, which should improve the frame rate of the game. Tips & Warnings Tip: The Superfetch technique will only work on Windows Vista.
