3D-Tech News Around The Web / AMD hopes to put a little Mantle in OpenGL Next

Announced earlier this week, the next-gen version of OpenGL is a complete, from-the-ground-up rewrite aimed at slashing overhead and giving developers more control over the hardware. In that sense, the upcoming API, which Huddy calls "OpenGL Next," will follow in the footsteps of Mantle and DirectX 12.

Huddy told us AMD has done a "great deal of work" with the Khronos Group, the stewards of the OpenGL spec, on OpenGL Next. AMD has given the organization unfettered access to Mantle and told them, in so many words, "This is how we do it. If you want to take the same approach, go ahead." Khronos is free to take as many pages as it wants out of the Mantle playbook, and AMD will impose no restrictions, nor will it charge any licensing fees.

3D-Tech News Around The Web / SIGGRAPH 2014: DirectX 12 on Intel

This week at SIGGRAPH 2014 Intel is showing a technology demo using Microsoft's upcoming DirectX 12 API that highlights the strong relationship between performance and power.

In the demo we render a scene of 50,000 fully dynamic and unique asteroids in one of two modes: maximum performance and maximum power saving. The application can switch between using the DirectX 11 and DirectX 12 APIs at the tap of a button. We are showing the demo in our SIGGRAPH booth running live on a Microsoft Surface Pro 3 tablet with an Intel® 4th Generation Core™ processor.

All of the results here were captured when the tablet was running in a steady, thermally-constrained state. This represents the experience of playing a demanding game for more than 10-15 minutes.
