Question 1

How to integrate vk-bootstrap into a CMake project?

Accepted Answer

Use FetchContent or add it as a git submodule, then link with target_link_libraries(your_app vk-bootstrap::vk-bootstrap). The README provides detailed examples for both methods, including handling Vulkan headers.

Question 2

vk-bootstrap vs Vulkan-Hpp: which should I use?

Accepted Answer

vk-bootstrap is best for simplifying initialization boilerplate, while Vulkan-Hpp provides C++ bindings for the entire Vulkan API. Use vk-bootstrap to jumpstart setup, but you might still need Vulkan-Hpp for type-safe Vulkan calls later.

Question 3

Does vk-bootstrap support Vulkan 1.2 or 1.3 features?

Accepted Answer

It supports Vulkan 1.1 by default, but you can specify higher versions using set_minimum_version(). However, enabling newer extensions or features may require manual configuration beyond the built-in helpers.

Question 4

How to handle errors when using vk-bootstrap?

Accepted Answer

Methods return expected types (e.g., vkb::Result); check for errors with if (!ret) and handle them, as shown in the basic usage example. This mirrors Vulkan's error handling but with simpler syntax.

Question 5

Can I use vk-bootstrap for compute-only applications without a display?

Accepted Answer

Yes, the simple_compute.cpp example demonstrates setting up a compute shader application without a surface by skipping swapchain creation and focusing on device and queue setup.

Question 6

What are the performance implications of using vk-bootstrap?

Accepted Answer

It adds negligible overhead as a thin wrapper over Vulkan API calls, but abstracts some low-level control, which might affect optimization in edge cases. For most applications, the trade-off is minimal.
