INCREASE CPU PRIORITY Recommended
for benchmarking
Changes the way Windows works with CPU resources. Increases performance for the primary application, and slightly neglects background services. Useful for benchmarking
INCREASE USB POLLING INTERVAL Recommended
for mobile users/benchmarking
Changes the latency of USB polling from 1ms to 5ms. Usable for some mobile users, as polling uses a fair slice of CPU performance. Hence, the CPU might not be able to enter a power-saving state. Likewise, it might be usable for benchmarkers because of a slightly reduced CPU load.
