@kamdroid When/if you lose the smoothness you've gained with 0.0166666 timers, it's because they've been rounded to 0.02, which sometimes happens just by touching them in the Behaviour Editor.
In this situation, you need to re-edit their time to 0.0166666.
Other times, you'll still be running smooth, but your timer behaviours show 0.02 seconds, rounded. This is because it's only a visual representation rounding UNTIL you touch them, when it becomes a physical rounding of this time.
Hope this helps. I've played with this, a lot, to get smooth and fast in hyperPad.
My advice, never use anything other than divisions and multipliers of frame time in timers. Unfortunately hyperPad doesn't let you use divisions of this, it rounds these up to a "tick", but not accurately, which is what it's doing if you put a zero in a timer.
Solving this problem, in the best possible way, would be providing accurate tick based timers, that can be divisions or multipliers of the underlying tick. This is going to be much more important later this year, when more iPads (and iPhones) move to ProMotion (120fps).
