Timer Resolution and DPC Latency

I’m told one of the uses for TimerResolution is to help reduce DPC Latency on Windows. This is supposed to improve performance of many games and applications.

I suspect that all that is really happening is that some poorly written drivers are getting a boost.

A great utility to check the DPC Latency on your system is http://www.thesycon.de/deu/latency_check.shtml, try it with and without TimerResolution running and see if it makes any difference on your system.
