Tested on Windows 11 (idle, same system, same conditions):
| Metric | Before | After | Improvement |
|---|---|---|---|
| CPU Load | 6% | 2–3% | ~60% less |
| CPU Clock | 1.60 GHz | 3.99 GHz | +149% |
| Processes | 195 | 180 | −15 |
| Threads | 3280 | 3220 | −60 |
| Handles | 80500 | 79850 | −650 |
The clock speed difference is the most significant — Windows was throttling the CPU in its default power plan. With the Ultimate Power Plan applied, the processor runs at full speed.
