m_uiCommandQueueMask

xiiUInt64 xiiGALTopLevelASCreationDescription::m_uiCommandQueueMask = XII_BIT(0)

Defines which command queues are allowed to execute commands that use this top level acceleration structure. The default is the main command queue. Only specify the bits that indicate those command queues where the resource will be used, setting unnecessary bits will result in extra overhead.
