Vkgetphysicaldevicefeatures2 |verified| Jun 2026

In Vulkan 1.0, developers were limited to the fixed VkPhysicalDeviceFeatures structure, which could not easily accommodate new features added by extensions.

: The "secret sauce." This pointer can point to another feature structure (e.g., VkPhysicalDeviceRayTracingPipelineFeaturesKHR ), creating a chain. vkgetphysicaldevicefeatures2

vkGetPhysicalDeviceFeatures2 is a masterpiece of API design regarding extensibility. It solved the "static struct" problem inherent in C APIs. While it introduces verbosity due to the manual management of the pNext chain, the flexibility it provides is essential for a low-level, cross-vendor API like Vulkan. In Vulkan 1

A robust Vulkan initialization routine should: It solved the "static struct" problem inherent in C APIs

Starting with Vulkan 1.1, vkGetPhysicalDeviceFeatures2 is guaranteed to be supported as a core function.

If you are maintaining Vulkan 1.0 code, you can still use vkGetPhysicalDeviceFeatures2 by checking for the VK_KHR_get_physical_device_properties2 extension. However, note that vkGetPhysicalDeviceFeatures2 may return different results than the legacy function for certain features (e.g., sparse binding capabilities) because the new function respects the full core version and extension interactions. For correctness, use only the new function.
