6 Best Ways to Fix NVIDIA OpenGL Driver Error Code 6

Errors may be a frustrating hurdle for gamers and many professionals who rely on the capabilities of NVIDIA graphics cards. One such error is the infamous NVIDIA OpenGL Driver Error Code 6. 

This error can cause crashes, graphical glitches, and a generally unpleasant gaming or working experience with graphically demanding apps. So if you are trying to play a game after a tiring night or just want to get some work done, and this error is not letting you, this is the right page.

We will go into the nitty-gritty of this error and provide you with a full tutorial on how to fix NVIDIA OpenGL Driver Error Code 6 and resume smooth, uninterrupted functioning.

Understanding NVIDIA OpenGL Driver Error Code 6

Before we dive into the solutions, let’s understand what NVIDIA OpenGL Driver Error Code 6 is all about. This error typically occurs when the graphics card encounters an issue with the OpenGL driver, which is a fundamental component for rendering graphics on your screen. The error message might appear as something along the lines of “NVIDIA OpenGL Driver Error: Code 6 (driver error code 6)”.

The error is often linked to the graphics card failing to allocate enough resources for the OpenGL context, leading to performance issues or crashes when running applications that heavily rely on OpenGL, such as many modern games and 3D modeling software.

Fix NVIDIA OpenGL Driver Error Code 6 

1. Restart Your PC

The first thing you can do when you encounter the NVIDIA OpenGL Driver Error Code 6 is restart your Windows PC. There is nothing that a good old restarting can’t fix. Restarting the PC will load all the files smoothly and make sure that your system runs error-free. 

2. Close Apps Using Too Much GPU Resources

  1. Press Ctrl + Shift + Esc on your keyboard, or alternatively, right-click on the taskbar and select Task Manager from the context menu.Close Apps Using Too Much GPU Resources
  2. In the Task Manager window, you’ll see several tabs. Click on the Processes tab.
  3. Look for the GPU column. 
  4. In the “GPU” column, you’ll see a percentage value indicating the GPU usage of each process. 

Note: Programs with higher percentages are the ones consuming more GPU resources. Observe the programs with high GPU usage. These are likely the culprits causing the slowdown.

  1. Select the program that you want to close. Click on it to highlight it.Select the program that you want to close. Click on it to highlight it.
  2. With the program selected, click the End Task button located in the bottom-right corner of the Task Manager window.
  3. Task Manager will attempt to close the selected program. If the program is unresponsive, Task Manager might prompt you to close it forcefully. Confirm by clicking End Task in the pop-up window.

3. Update the GPU Driver

The first step in resolving any graphics-related issue is to ensure that your graphics drivers are up to date. Outdated drivers can lead to compatibility problems and errors. Head over to the official NVIDIA website and download the latest drivers for your graphics card model. Install the drivers and reboot your system.

4. Adjust Graphics Settings

Oftentimes, especially in laptops, the default graphics settings are made to optimize the battery life, and that is why the GPU doesn’t perform to the max. Here is how you can enhance the GPU performance capabilities through settings: 

  1. Open the NVIDIA Control Panel by right-clicking on your desktop and selecting it from the context menu. Adjust Graphics Settings
  2. Under the 3D Settings section, go to Manage 3D Settings.3D Settings section, go to Manage 3D settings
  3. In the Global Settings tab, locate the Power management mode 
  4. Set it to Prefer maximum performance Prefer maximum performance
  5. Apply the changes and check if the error persists.

5. Install Clean Drivers

If updating the drivers didn’t work, a clean installation might do the trick. Now there is a way to do this on your own, but it might not be as effective in uninstalling the drivers completely. 

You can use a tool like Display Driver Uninstaller (DDU) to uninstall your current drivers completely. After that, install the latest drivers from NVIDIA’s website.

6. Check for Hardware Issues

Oftentimes, it is the hardware issues causing the problems, but they get overlooked. So the better thing is to check for any hardware issues as well. 

  • Temperature Monitoring: Overheating can cause various issues, including OpenGL errors. Install a temperature monitoring tool like MSI Afterburner and monitor your GPU temperature while running demanding applications. If the temperature is reaching critical levels, consider cleaning your GPU and improving airflow in your PC case.
  • Reseat the GPU: Sometimes, a loose connection can cause errors. Power off your computer, open the case and carefully reseat the graphics card in its PCIe slot. Make sure it’s properly secured.


The NVIDIA OpenGL Driver Error Code 6 might be a daunting challenge, but armed with the right knowledge and troubleshooting steps, you can overcome it. Remember, while technology can be frustrating at times, there’s always a solution waiting to be discovered. By updating drivers, adjusting settings, and checking for hardware issues, you’re on the path to smoother gaming and a more enjoyable computing experience.
