If a timer is requested with <=100ms resolution, request the high-res timer. Since the default Windows timer period is 15ms, this means a 100ms timer could fire at 115ms (15% late). We assume that timers longer than 100ms are a reasonable cutoff here. The high-res timers on Windows are still limited. Unfortuntely this means that our shortest duration 4ms timers can still be 25% late, but without a more complex timer system or spinning on the clock itself, we're somewhat bounded by the OS' scheduler itself. |
