    I test prject on device OnePlus 3T (build number A3003_28_170610), OxygenOS 4.1.6, Android 7.1.1
    With OpenGLES3 - 60 fps stable
    With Vulkan - 30-60 fps jumps
    If Graphics Jobs enabled, fps 12-40, very slow

    Agreed, we haven't seen any performance improvements in either of our real world projects. Enabling Vulkan just degrades performance by atleast 25-50%.

    I've reached the same conclusion as you guys in my test projects

    Tested a Windows 64-bit build switching from DirectX 11 to Vulkan, and frame rate was chopped in half. Not sure what's going on, but will wait a while and try this stuff again in a few months.

    Hi, we're working on Vulkan performance, and all real-world testing content would be welcome. Those of you who are able to send your projects over, please file a bug and PM me the bug ID so we can take a look. If possible, strip out all plugins and extra stuff you're running to make the project upgrades as easy as possible (I'll be running them in 2018.2 -based environment)

    Thanks!
