We appreciate your active participation in the Microsoft Community. Yes, the Surface Pro 9 (QIA-00004) is compatible with OpenGL. You can install OpenGL on the device to run applications that require it. However, please note that Microsoft does not provide support for third-party software such as OpenGL. If you encounter any issues with the installation or use of OpenGL, you may need to contact the software vendor for assistance. For the Surface Pro9 5G Please check this link opengl 3.1 or higher for windows 11 surface pro x - Microsoft Community
