Does HPET Cause Input Lag?
HPET (High Precision Event Timer) is a feature in modern computers that is designed to provide accurate timing and synchronization for various system functions. While it is primarily used by the operating system and applications, it can also have an impact on gaming performance.
When HPET is enabled, it introduces a small delay of around 0.1 to 0.15 milliseconds. This delay is caused by the timer interrupt that HPET uses to keep track of time. While this delay may seem insignificant, it can add up over time and lead to noticeable input lag during gameplay.
Input lag refers to the delay between when you perform an action, such as pressing a key or moving the mouse, and when it is registered by the system. In gaming, even the slightest delay can have a significant impact on performance, as it can affect the timing and responsiveness of your actions.
By disabling HPET, you can reduce this input lag and potentially gain a few extra frames per second (FPS) in your games. While the increase in FPS may not be significant on its own, it can help to improve overall gameplay smoothness and reduce the occurrence of micro-stuttering.
Micro-stuttering is a phenomenon where the frame rate fluctuates irregularly, causing small but noticeable hiccups in the visuals. This can be particularly frustrating during fast-paced games where fluid motion is crucial.
It is worth noting that the impact of HPET on gaming performance can vary depending on the specific hardware and software configuration of your system. Some users may not experience any significant difference in input lag or FPS by disabling HPET, while others may observe a noticeable improvement.
While HPET does introduce a small delay that can contribute to input lag and potentially affect gaming performance, the actual impact can vary from system to system. If you are experiencing input lag or micro-stuttering in your games, disabling HPET may be worth considering as a potential solution. However, it is always recommended to test the impact on your specific system before making any permanent changes.
