How Do I Fix Unable to initialize OpenGL?

What is OpenGL?

OpenGL, short for Open Graphics Library, is a cross-language, cross-platform application programming interface, to render 2D and 3D vector graphics. Applications use OpenGL in computer-aided design, virtual reality, scientific visualization, and video games, etc.

Method 1: Update the graphics card driver

The graphics card issue can generally cause the problem of unable to initialize OpenGL. If the video driver in your computer is missing or out of date, it can result in this problem and stop running the application or game. You can try to update the graphics card driver to fix the error.

There are two ways to update the graphics drivers: manually and automatically.

Manually update the driver: you can go to the manufacturer’s website, find the latest driver that is compatible with your variant of Windows system, then install it in your computer. this requires time and computer skills. Since the graphic card drivers vary from manufacturer to manufacturer, and from device model to device model, so we won’t cover it here.

Automatically update the driver: if you don’t have the time, patience or computer skills to update the graphics card driver manually, you can do it automatically with Driver Easy.

3) Click the Update button next to the driver name to download the correct driver (you can do that with the FREE version), then install it in your computer.

Or click Update All to automatically download and install the correct version of all the problem drivers (you can do that with Pro version, and you will be prompted to  upgrade when you click Update All).

4) Launch the game that gives the error again.

Method 3: Modify the settings in the game

This method works for many users. If you encounter the error “Failed to initialize OpenGL“, or “Unable to initialize openGL window“, you can try this solution to fix it.

Since the game varies, we take the No Man’s Sky as an example.

1) Right click the name of the game in steam, and go to Properties. 2) Go to LOCAL FILES and click BROWSE LOCAL FILES. 3) Go into Binaries > Settings, and open mxml.

4) Change FullScreen from true to false.


5) On the same settings pane, lower your resolution to what your screen resolution is.

For example, if your screen resolution is 1280×768, you can change ResolutionWidth to 1280, and change ResolutionHeight to 768.


6) Save the settings and restart the game to see if it works.
