AMD suggests developers focus on Direct X 12 or OpenGL instead.
According to one report, DirectX 12 will support Explicit Asynchronous Multi-GPU capabilities across different manufacturers’ GPUs.
Microsoft has appeared to have developed a viable competitor to AMD’s Mantle if the benchmarks displayed at Intel’s SIGGRAPH booth in Vancouver are consistent with real-world performance. According to benchmarks and a demo ran at Intel’s SIGGRAPH booth, DirectX 12 offers a 70% boost in performance over DirectX 11 and offers substantial power savings to0. The demo run was a graphically intense simulation of what appears to be an asteroid belt with 50,000 asteroids rendered on screen. This is similar to AMD’s demo of Star Citizen — where tens of thousands of individual ships are rendered in a big dogfight — that it uses to
