Features

🧩 The Nabla Core Profile

Nabla exposes a curated set of Vulkan extensions and features compatible across the GPUs we aim to support on Windows, Linux, (coming soon MacOS, iOS as well as Android)

Vulkan evolves fast—just when you think you've figured out sync, you realize there's sync2. Keeping up with new extensions, best practices, and hardware quirks is exhausting. Instead of digging through gpuinfo.org or Vulkan specs, Nabla gives you a well-thought-out set of extensions—so you can focus on what you want to achieve, not get stuck in an eternal loop of:

mastering a feature
finding out about a new feature
assesing whether obsoletes or just adds the one you've just mastered
working if the feature is ubiquitous on the devices you target
rewriting what you've just polished

🧩 Physical Device Selection and Filteration

Nabla allows you to select the best GPU for your compute or graphics workload.

void filterDevices(core::set<video::IPhysicalDevice*>& physicalDevices)
{
  nbl::video::SPhysicalDeviceFilter deviceFilter = {};
  deviceFilter.minApiVersion = { 1,3,0 };
  deviceFilter.minConformanceVersion = {1,3,0,0};
  deviceFilter.requiredFeatures.rayQuery = true;
  deviceFilter(physicalDevices);
}

🧩 SPIR-V and Vulkan as First-Class Citizens

Nabla treats SPIR-V and Vulkan as the preferred, reference standard—everything else is built around them, with all other backends adapting to them.

🧩 Integration of Renderdoc

Built-in support for capturing frames and debugging with Renderdoc. This is how one debugs headless or async GPU workloads that are not directly involved in producing a swapchain frame to be captured by Renderdoc.

const IQueue::SSubmitInfo submitInfo = {
    .waitSemaphores = {},
    .commandBuffers = {&cmdbufInfo,1},
    .signalSemaphores = {&signalInfo,1}
};
m_api->startCapture(); // Start Renderdoc Capture
queue->submit({&submitInfo,1});
m_api->endCapture(); // End Renderdoc Capture

🧩 Nabla Event Handler: Seamless GPU-CPU Synchronization

Nabla Event Handler's extensive usage of Timeline Semaphores enables CPU Callbacks on GPU conditions.

You can enqueue callbacks that trigger upon submission completion (workload finish), enabling amongst others, async readback of submission side effects, or deallocating an allocation after a workload is finished.

// This doesn't actually free the memory from the pool, the memory is queued up to be freed only after the `scratchSemaphore` reaches a value a future submit will signal
memory_pool->deallocate(&offse
