Running GTA IV in windowed mode

If you’re encountering the issue on a newer configuration, chances are GTA IV is not optimized to run on your native resolution. This problem should have been resolved with the update pushed for Windows 10, but some users are reporting that they can only run the game if they force the executable to run in ‘windowed’ mode.

Sure, the immersion will be less than ideal since you will see borders, but it’s still better than being unable to play the game at all.

Keep in mind that when it comes to doing this, you can either do it directly from your Steam client or by modifying the shortcut that you use to launch the game.
