The last time I had out this particular system with i7-5600 CPU sporting HD Graphics 5500, the Vulkan experience wasn't really working out at that time. But a half-year has passed and now it's in better shape for this low-power ultrabook.
I ran tests with the Linux 4.10 and Mesa 13.1-devel Git stacks atop Ubuntu 16.10 x86_64.
The HD Graphics 5500 on this i7-5600U ultrabook aren't the fastest, but at 800 x 600 for Dota 2 we see the performance is about the same between the Vulkan and OpenGL drivers.
Still close at 1280 x 1024.
The performance is rather low, but those are the numbers for those always craving fresh Intel graphics results.
Unfortunately no Talos Principle results for Vulkan as the game was hanging in this configuration.
Still working on some other fresh tests with Iris Pro Graphics as well as the Skylake HD Graphics that provide for more playable Linux OpenGL/Vulkan gaming experience. Great to see overall though how the Intel "ANV" Vulkan driver has matured this year and is quite a competent driver while the i965 Mesa driver has also advanced in 2016 to supporting OpenGL 4.5, performance optimizations, and other improved functionality.
