And so far there's no OpenGL-4 software rasterizer. If your GPU can't to OpenGL-3 or OpenGL-4 then all you could do is fall back to a software implementation. However the limiting part is the capabilities of your GPU. I tried to update my processor driver too but uselessly I get the same message, that my driver is updated.
I tried to update my Graphics drivers from 'Drivers Manager' under windows but it tells me that I have the latest version. This fixes many OpenGL issues on Windows. On Windows 10, starting with the May 2019 Update, you can use Windows Sandbox, a feature that offers a lightweight environment isolated from your main installation, to run untrusted applications. Try updating to your latest OpenGL graphics driver. So updating the driver may give you a major version bump. I installed OpenGL Extensions Viewer and it shows me that i have OpenGL 2.1. However, if you are getting display/refresh problems, and theyre only occuring on windows, this is most likely an issue with your graphics driver. Of course the OpenGL driver itself is part of the implementation. library which allows the user to create and manage windows containing OpenGL contexts on a wide. Or in other words: A OpenGL implementation implemented along the OpenGL-3 specification will not be capable of OpenGL-4 (OTOH minor version bumps are within the capabilities of a given major implementation feature set the mostly clean up the API or give access to things which were already possible (and maybe accessible through extensions) but not formally specified in core). You can update the drivers with the help of this tool.
a major capability bump on the implementation side. Since version 3 the major version number of OpenGL is equivalent to feature capabilities, i.e. it doesn't matter in which way it's implemented) the authors of the OpenGL specification clearly target special purpose hardware (aka GPUs). While the OpenGL specifications are written implementation neutral (i.e.
