Changing Default Resolution of Windows Timer To Increase Graphics Speed

[DaveS]

perhaps this helps?

A timer tick is a notion of elapsed time that Windows uses to track the time of day and thread quantum times. By default, the clock interrupt and timer tick are the same, but Windows or an application can change the clock interrupt period.

The default timer resolution on Windows 7 is 15.6 milliseconds (ms).

plus if your refresh rate exceeds that of the monitor you should not be able to percieve a flicker… for that matter, if your FPS exceeds even 24fps it should be hard to percieve it… since that is the retention period of most peoples eyes (and why movies were shot at that speed (on film)…digital is faster these days)
