I was developing Vulkan code against the Apr 19 beta driver. I recently upgraded to the latest drivers for my Radeon 270X and saw performance of my test case go from 1500 fps to 500 fps. A friend tried the latest driver on his 290, and saw an even more extreme problem -- the demo went from 2500 fps to 100 fps (one hundred!)
Is the 16.7.3 driver really that much slower than the Beta for Vulkan? Why?
Thanks for any info.
