Vulkan is the new big exciting Thing That Might Make Your Games Run Faster Without You Having To Buy A New Graphics Card Or Anything, Jeremy recently explained in slightly more technical detail, and now Dota 2 [official site] supports the new graphics API too. In beta. And it might not make a difference for you. Or may be worse. If you want to be on the bleeding edge of technology (a phrase which always makes me think of eXistenZ and meatcomputers), you can now download and try Dota 2’s Vulkan beta.
