    Question Windows and Linux differences

    I have an Intel Celeron N2920 processor, which on Windows (I confirm this) uses OpenGL 4.0 (without Vulkan and without OpenCL, because I did not download the CL SDKs).

    Reading here:

    I realized that my built-in/integrated video card supports OpenGL 4.2, ES 3.0 and Vulkan, but only on Linux.

    How is this possible? If I do Dual-Boot, how can I download the drivers for OpenGL 4.2, ES 3.0 and Vulkan on Linux? Just by downloading the "Additional Drivers", will at least OpenGL 4.2 be on my computer (Linux Boot)? :D

    I hope it's true, what do you guys tell me? Or help?

    Thanks! ^^

    OpenGL, OpenGL ES, and Vulkan are APIs implemented by drivers. Driver support (and sometimes who wrote the drivers) varies per OS.

    According to the Archlinux wiki, Vulkan support for your Intel under Linux is provided by vulkan-intel, which is provided by the famous Mesa3D graphics drivers. More on that here in Mesa3D Intro:
