Are there any DirectX games of Windows 7 have passed Intel's Power Checker?
To ask an APP change Platform Timer Resolution is unreasonable.
An User Level App can not change Platform Timer Resolution. It is the Operating System and Driver's duty. The default Timer Resolution of Windows is 15.6ms. But when an App such as a game used DirectX or multimedia functions, the Platform Timer Resolution is set to 1ms. That is for performance and accurate time control of media playback. It is good for power effeciency to set the timer resolution as 15.6ms when a player or a game is in idle. But how could an app programmer to do this? There is no API to set Platform Timer Resolution. A driver programer can do this by using ExSetTimerResolution. Intel can open an API through its driver but it opens a security hole as well.
Note that the result of changing the clock interrupt frequency is
system-wide and can have a severely negative effect on system
performance. Also note that higher clock interrupt frequencies can
shorten a system's battery life.
In summary to apply Platform Timer Resolution as a metric for Power Checker Testing is unreasonable. It is not the duty of an App to modify the Platform Timer Resolution.
