Lower CPU usage and power consumption significantly when SPUs are waiting for SPURS tasks. This is because when Acuurate SPU Resevations are disabled all reservation writes notify the SPU, so it's possible to drop the timeout on sleep condition, making the SPUs able to be fully relaxed. This requires "Accurate SPU Reservations: false" in config.
