when returning from holiday, I wanted to run the examples of the github-repo of Sascha Willems (https://github.com/SaschaWillems/Vulkan) with my NVidia GTX 970, currently with the extra/nvidia driver, version 361.28-4.
Unfortunately all examples crush at Vulkan/base/vulkanexamplebase.cpp:677: void VulkanExampleBase::initVulkan(bool) when calling vkEnumeratePhysicalDevices(); the error-code evaluates to
VK_ERROR_INITIALIZATION_FAILED, but vkCreateInstance() returns w/o errors.

Does anyone has similar issues or an idea, what am i doing wrong?

Thanks a lot!
