Wasanni da Vulkan

Karshen 16 ga Fabrairu Croteam ya ƙaddamar da Taa'idar Talos, sanya a cikin Steam dandamali amfani da Injin Vulkan. Abin takaici sigar wannan wasan don Linux ba ta fito fili ba, amma anjima zai kasance

Daga Bawul, ana kuma tsammanin hakan Dota2 zama da ewa ba samuwa Tare da tallafi aman wuta, kamar yadda sauran wasannin zasu bayyana nan gaba.

Michael Larabil, marubucin dandali Phoronix yi sharhi cewa “a matsayin mai haɓaka wasanni wanda ke da hannu a cikin aman wuta An yi musu gargaɗi babu riya sa ran mu'ujiza tare da wasan Vulkan”. Wannan saboda Vulkan API yana ba da dama da yawa don ingantaccen aiki da haɓakawa, wasanni da injunan su ana kan hanya don DirectX 11 da OpenGL. Bazai kasance ba har sai bayyanar sabbin wasanni ko kuma injunan da aka sake fasalta aman wuta cewa za a yi mafi kyawun aiki a OpenGL / DX11.
