     3== rdtscTimeSource for high precision timer counters ==

     5The plugin changes the default time source of the engine against a time source based on the fetching of the '''rdtsc''' instruction of the CPU.  
     6 
     7'''''Warning:''''' on CPUs with dynamicly changeable frequencies the timers may run incorrect 
     8 
     9Following parameters can be given to the plugin during the initialization: 
     10 * ''sync_interval'' [uint32]: time in milliseconds which can be passed untill the next synchronization. On CPUs with stable frequency this value can be set to 0. Default value is 500 
     11 * ''sync_duration'' [uint32]: time in milliseconds how long the frequency measurement (i.e. synching) has to take place. Shorter values can produce incorrect results of the CPU speed. Default value is 10ms.
