NVIDIA zaten bir OpenGL 4.5 sürücüsünü sahipken, Khronos Group OpenGL 4.5’i duyurdu. Açık kaynak öncesi Mesa/Gallium3D sürücülerinin uzun süreli olarak OpenGL 4.5 uyumluluğunun iddia edilebileceği ifade edildi. Bu, OpenGL 4.5 adına Khronos Group ile GL için yeni bir grafik API, AMD’nin Mantle’i, Microsoft’un DirectX 12’sini içeren evrimsel bir güncelleme oldu. Daha fazla bilgi edinmek için son OpenGL 3/4 belgelerini inceleyebilirsiniz.
