Microsoft has introduced a new toggle in Windows 11 that prioritizes low latency over power efficiency. The feature, which is currently available in the latest Insider builds, is designed to reduce input lag. This change was made available on June 28, 2026.
The new low latency mode is essentially a brute-force CPU boost that increases processing power at the expense of energy efficiency. By doing so, it aims to minimize delays between user input and the corresponding system response.
When the low latency mode is enabled, the CPU is allowed to run at higher frequencies for longer periods, resulting in increased power consumption. This approach is straightforward but comes with a significant drawback: it wastes power. The increased power usage may not be a concern for desktop users, but it could be a significant issue for laptop users who rely on battery life.
The effectiveness of this feature is also debatable, as the reduction in input lag may not be noticeable to most users. In many cases, the human perception of latency is limited, and the benefits of this feature may be imperceptible.
The decision to implement a feature that prioritizes performance over power efficiency raises questions about its overall value. While it may be beneficial for specific use cases, such as gaming or video editing, it may not be justified for general use.
As a result, users may need to weigh the benefits of reduced input lag against the potential drawbacks of increased power consumption. For some, the trade-off may be acceptable, while for others, it may not be worth the cost.
