    vkCreateGraphicsPipelines performance in 16.9.1




      When I upgraded my drivers from 16.8.1 to 16.9.1, the Vulkan implementation I am writing plummeted from a ~4-6 ms frame time to 76 ms. It seems that sometimes, vkCreateGraphicsPipelines takes up to 25 ms to complete, and the performance is the same with a pipeline cache as without, meaning that the speedup gained from using a pipeline cache seems to be lost.
