Using the WDK provides several benefits, including:
BOOLEAN ProcessCompletionQueue(PGRAPHICS_DEVICE_EXTENSION devExt) { ULONG processed = 0; ULONG maxPerBatch = 32; while (processed < maxPerBatch && !IsQueueEmpty(devExt)) { ProcessOneCompletion(devExt); processed++; } windows wdk
She had tried everything: optimizing the event handling, using lookaside lists for memory allocation, even rewriting critical sections in assembly. Nothing worked. The latency was caused by a hardware limitation: the GPU's completion queue could only be read at a certain speed, and when it overflowed, her driver had to drain it.

He simulated the sleep command.
Oh, sweet summer child.
No blue screen.
