Oxide Games has been mentioned all throughout the development of the next-generation graphics APIs, DirectX 12, Mantle, and Vulkan. Their Star Swarm “stress test” was one of the first practical examples of a game that desperately needs to make a lot of draw calls. Also, their rendering algorithm is very different from the other popular game engines, where lighting is performed on the object rather than the screen, which the new APIs help out with.
Currently, Ashes of the Singularity supports DirectX 11 and DirectX 12, but Vulkan will be added soon. Oxide will be pushing the new graphics api in the 2.4 update, bringing increased CPU performance to all OSes but especially Windows 7 and 8 (neither of which support DirectX 12), and a free DLC pack that contains nine co-op maps. They also plan to continue optimizing Ashes of the Singularity for Vulkan in the future.
All of this will be available on Thursday, August 24th.
