Vulkan® 1.3.264 - A Specification (with all registered extensions)

Appendix F: Vulkan Roadmap Milestones

Roadmap milestones are intended to be supported by mid-to-high-end smartphones, tablets, laptops, consoles, and desktop devices.

Each milestone indicates support for a set of extensions, features, limits, and formats across these devices, and should be supported by all such new hardware shipping by the end of the target year or shortly thereafter.

Roadmap 2022

The Roadmap 2022 milestone is intended to be supported by newer mid-to-high-end devices shipping in 2022 or shortly thereafter across mainstream smartphone, tablet, laptops, console and desktop devices.
