ImportMemoryWin32HandleEXT unsupported

[1zun4]

Hi,

I'm currently trying to convert a d3d11 shared texture (CEF process) to my OpenGL game. This was proven to work on a NVIDIA GPU with their Windows drivers, however, it does not seem to be supported on the Intel GPU driver for Windows.

Issue description:

ImportMemoryWin32HandleEXT on EXT_external_objects_win32 unsupported.

Hi 1zun4,

Thank you for reaching out to the Intel Community Forum. To assist us in investigating the issue, please provide the following details:

• When did the issue start?
• What are the troubleshooting steps that you tried so far?
• Is the Resizable Bar enabled?
• Have you used DDU to completely remove all residual drivers and installed a new one?

Additionally, to gain a comprehensive understanding of your system, please use the System Support Utility (SSU). This tool will generate a text file compiling all your system information. You can follow the instructions at this link and send the text file here. Help Guide for the Intel® System Support Utility.

If you have any questions, please let us know. Thank you.

Hi @ArchieD_Intel ,

Thank you for the response, but this isn't a driver corruption or hardware configuration issue that can be fixed with DDU or system diagnostics. This is a missing API feature where Intel's OpenGL driver simply doesn't implement the GL_EXT_memory_object_win32 extension for D3D11/D3D12 interoperability, which works fine on NVIDIA hardware. What I need is confirmation from Intel's driver team about whether these OpenGL extensions are planned for implementation, not troubleshooting steps for a broken driver.
