Bethesda recently released an update for DOOM which allows gamers to finally take advantage of the Vulkan API. The guys over at ComputerBase.de ran some tests to see how the Vulkan API compared to the default OpenGL and it reveals that Vulkan benefits AMD GPUs far better than NVIDIA ones.
The 2560 x 1440 resolution an AMD Radeon R9 Fury X with Vulkan is 25 percent faster than a GeForce GTX 1070 with Vulkan. When running OpenGL the AMD Radeon R9 Fury X is actually 15 percent slower than the GTX 1070. The Vulkan API increases the R9 Fury X’s frame-rates over OpenGL by a staggering 52 percent! Similar results were found at 1080p resolution as well.
