When the number of polygons was around 80k, it was found that the Direct3D offers the same kind of performance as OpenGL. When this number went above 80k, OpenGL was found to be much faster.

Some of the efficiency improvements will come from “closer to the metal” access to the hardware in DirectX 12, though NVIDIA will also be improving performance in DX11 and OpenGL with future ...

OpenGL and DirectX most likely will be following AMD Mantle API's footsteps by providing low-level access for video cards.

Just four and a half months after releasing the OpenGL 4 specification, the Khronos Group has released the final version of the OpenGL 4.1 specification. OpenGL 4.0 brought feature parity with ...

"Why does an OpenGL version of our game run faster than Direct3D on Windows 7? It appears that it's not related to multitasking overhead," Valve's Linux team wrote.

Originally developed for professional applications by Silicon Graphics, as a replacement for its IRIS GL, OpenGL quickly became the go-to API for 3D games until Microsoft launched Direct3D for its ...

AMD (almost) rolls out Mantle, its high performance alternative to Direct3D and OpenGL Battlefield 4 framerates boosted by as much as 58 percent in CPU-bound situations.

The Khronos Group has announced the release of OpenGL 3.2, a new version of the 2D and 3D graphics specification Apple uses in Mac OS X.

Valve will be speaking about its Linux/OpenGL advancements at SIGGRAPH 2012 next week. SIGGRAPH is where we usually hear about the latest OpenGL and DirectX news, too -- so stay tuned!
