DeepSea Render Vulkan provides the Vulkan implementation of the renderer.
Graphics debuggers, such as RenderDoc and NVIDIA Nsight Graphics can be very useful tools for tracking down rendering problems or performance bottlenecks. However, you will sometimes run into problems when running with a debug build with validation enabled. For example, NVIDIA Nsight will hang indefinitely when capturing a frame.
DeepSea will automatically detect when RenderDoc is attached and disable validation. For other tools, you should set the DS_DISABLE_VULKAN_VALIDATIONS=1 environment variable in the application launch options to disable the validation layers.
