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().
