Vulkan on Linux didn't work with my custom 4.5 or 4.4 Kernel
It works fine on the stock Xubuntu 4.2 lowlatency kernel though.
UPDATE: Nvidia has corrected the bug in version 353.00.29. I had even used the -x switch to extract the driver, add some optimizations during it's brief module compiling process and possibly made the system faster. Before Vulkan, I could not play Bioshock Infinite on Ultra. After, I could. Great job!
