Member Variable Documentation

quint32 QRhiStats::allocCount

Statistic reported from the Vulkan or D3D12 memory allocator.

See also QRhi::statistics().

quint32 QRhiStats::blockCount

Statistic reported from the Vulkan or D3D12 memory allocator.

See also QRhi::statistics().

qint64 QRhiStats::totalPipelineCreationTime

The total time in milliseconds spent in graphics and compute pipeline creation, which usually involves shader compilation or cache lookups, and potentially expensive processing.

Note: The value should not be compared between different backends since the concept of "pipelines" and what exactly happens under the hood during, for instance, a call to QRhiGraphicsPipeline::create(), differ greatly between graphics APIs and their implementations.

See also QRhi::statistics().

quint64 QRhiStats::totalUsageBytes

Valid only with D3D12 currently. Matches IDXGIAdapter3::QueryVideoMemoryInfo().

See also QRhi::statistics().

quint64 QRhiStats::unusedBytes

Statistic reported from the Vulkan or D3D12 memory allocator.

See also QRhi::statistics().

quint64 QRhiStats::usedBytes

Statistic reported from the Vulkan or D3D12 memory allocator.

See also QRhi::statistics().
