DynamicHeapPageSize

Uint32 Diligent::EngineWebGPUCreateInfo::DynamicHeapPageSize = 256 << 10

Size of the memory chunk suballocated by immediate/deferred context from the global dynamic heap to perform lock-free dynamic suballocations.

DynamicHeapSize

Uint32 Diligent::EngineWebGPUCreateInfo::DynamicHeapSize = 8 << 20

The size of the dynamic heap (the buffer that is used to suballocate memory for dynamic resources).

The dynamic heap is used to allocate memory for dynamic resources. Each time a dynamic buffer or dynamic texture is mapped, the engine allocates a new chunk of memory from the dynamic heap. At the end of the frame, all dynamic memory allocated for the frame is recycled. Note that unlike Vulkan, the dynamic memory becomes available immediately for use in the next frame.

UploadHeapPageSize

Uint32 Diligent::EngineWebGPUCreateInfo::UploadHeapPageSize = 8 << 20

Upload heap page size.

Upload heap is used to update resources with IDeviceContext::UpdateBuffer(), IDeviceContext::UpdateTexture(), or to map dynamic textures.
