Learn how to configure additional command line arguments for (GTA V) Grand Theft Auto V to improve performance, stability, and debugging. This guide walks you through the step-by-step process with practical tips for both Steam and Rockstar versions.

How To Set Up Additional Command Line Arguments on GTA V

Whether you want to improve performance, enable specific debugging tools, or tweak graphical settings, setting up command line arguments for GTA V can give you better control over how the game behaves at launch. This tutorial covers everything you need to know to get started with command line arguments for Grand Theft Auto V on both Steam and Rockstar Games Launcher.

🔧 What Are Command Line Arguments?

Command line arguments are custom launch instructions that modify how the game loads and behaves. They are placed in a special file called commandline.txt within the Grand Theft Auto root directory. These options do not change gameplay, but they significantly affect startup parameters like screen resolution, GPU usage, and system resource allocation.

🗂️ Step 1: Locate Your GTA V Installation Folder

First, you need to find the folder where GTA V is installed.

• Steam Version:
  C:\Program Files (x86)\Steam\steamapps\common\Grand Theft Auto V
• Rockstar Games Launcher Version:
  C:\Program Files\Rockstar Games\Grand Theft Auto V

Navigate to this folder using File Explorer.

📝 Step 2: Create or Edit commandline.txt

In your Grand Theft Auto directory, look for a file named commandline.txt.

• If it already exists, right-click and open it with Notepad.
• If it doesn’t exist, create a new text file and rename it to commandline.txt.

Ensure that file extensions are visible in your system settings, so the file is not mistakenly named commandline.txt.txt.

⚙️ Step 3: Add Command Line Options

You can now enter the desired command line arguments into this file. Each argument should be on a new line. Here are some commonly used ones:

-nosplash
-nomousegrab
-ignoreDifferentVideoCard
-windowed
-width 1920
-height 1080
-refresh 60
-frameLimit 0
-borderless

Explanation of Key Arguments

• -nosplash: Skips the Rockstar splash screen.
• -windowed: Launches the game in windowed mode.
• -borderless: Runs windowed mode without borders.
• -width & -height: Sets custom screen resolution.
• -frameLimit: Controls FPS cap (0 = uncapped).
• -ignoreDifferentVideoCard: Useful if switching GPUs or using external ones.
• -disableHyperthreading: May help on older CPUs.

🎮 Step 4: Save GTA V and Launch

Once you’ve added your desired commands, save the file and launch game from your usual shortcut. The game will automatically detect and apply the instructions in commandline.txt.

💡 Pro Tips

• Test one setting at a time if you’re troubleshooting crashes or FPS drops.
• Use -benchmark to run the built-in performance benchmark.
• Back up your commandline.txt before testing experimental settings.

❗ Important Notes

• Some command line arguments might become outdated with game updates.
• Rockstar doesn’t officially document all arguments, so use with caution.
• If the game crashes or fails to launch, remove the last argument you added.

🧠 Why Use Command Line Arguments?

Using launch parameters is ideal for:

• Improving compatibility on low-end systems.
• Forcing performance tweaks without using in-game settings.
• Automating launch settings across multiple installations.
