A 720m GPU will support many new extensions that your 520m GPU does not, but at the same time they can both implement all of the required functionality from GL 4.4. This is why GL has extensions in addition to core versions. Until things are standardized across all of the vendors who are part of the ARB, some features of GPU hardware are unusable in core GL. There may be optional ARB extensions introduced with the yearly release of new GL version specifications, but until they are promoted to core, GL does not require support for them. AMD's solution to this "problem" was to introduce a whole new API (Mantle) that more closely follows the feature set of their Graphics Core Next-based architectures more of a console approach to API design. This is because they are designed around supporting the most hardware possible rather than all of the features of one specific piece of hardware. OpenGL still lacks support for some features introduced in Direct3D 11 and likewise Direct3D 11.x lacks support for some OpenGL 4.x features and neither API fully exposes the underlying hardware. In fact, core GL often lags a generation or more behind HW capabilities in required functionality. Every new generation of GPUs generally adds new HW features, but the features exposed by every new version of OpenGL do not necessarily require new HW. You could say that the progress in graphics APIs with respect to hardware functionality has stopped since Fermi. Or I do not understand it clear? And so what does it mean that my video card is supported openGL 4.x? Vendors try to find ways to accelerate video cards in hw level and add functions that use it.

#Opengl 4.4 vs 4.5 update#
Why vendors realize new video cards if they can update openGL to add new function? I think it is untruth. Product is based on a published Khronos Specification and has been submitted to, and is expected to pass, the Khronos Conformance Process.According to you, the progress in video cards stopped since the fermi architecture. This package supports apps that use OpenCL version 1.2 and earlier and OpenGL version 3.3 and earlier.
#Opengl 4.4 vs 4.5 driver#
If a DirectX 12 driver is installed, supported apps will run with hardware acceleration for better performance.
