- /* It turns out that [ScreenSaverView setAnimationTimeInterval] does nothing.
- This is bad, because some of the screen hacks want to delay for long
- periods (like 5 seconds or a minute!) between frames, and running them
- all at 60 FPS is no good.
-
- So, we don't use setAnimationTimeInterval, and just let the framework call
- us whenever. But, we only invoke the screen hack's "draw frame" method
- when enough time has expired.
+ /* It turns out that on some systems (possibly only 10.5 and older?)
+ [ScreenSaverView setAnimationTimeInterval] does nothing. This means
+ that we cannot rely on it.
+
+ Some of the screen hacks want to delay for long periods, and letting the
+ framework run the update function at 30 FPS when it really wanted half a
+ minute between frames would be bad. So instead, we assume that the
+ framework's animation timer might fire whenever, but we only invoke the
+ screen hack's "draw frame" method when enough time has expired.
This means two extra calls to gettimeofday() per frame. For fast-cycling
screen savers, that might actually slow them down. Oh well.
- #### Also, we do not run the draw callback faster than the system's
- animationTimeInterval, so if any savers are pickier about timing
- than that, this may slow them down too much. If that's a problem,
- then we could call draw_cb in a loop here (with usleep) until the
- next call would put us past animationTimeInterval... But a better
- approach would probably be to just change the saver to not do that.
+ A side-effect of this is that it's not possible for a saver to request
+ an animation interval that is faster than animationTimeInterval.
+
+ HOWEVER! On modern systems where setAnimationTimeInterval is *not*
+ ignored, it's important that it be faster than 30 FPS. 120 FPS is good.
+
+ An NSTimer won't fire if the timer is already running the invocation
+ function from a previous firing. So, if we use a 30 FPS
+ animationTimeInterval (33333 µs) and a screenhack takes 40000 µs for a
+ frame, there will be a 26666 µs delay until the next frame, 66666 µs
+ after the beginning of the current frame. In other words, 25 FPS
+ becomes 15 FPS.
+
+ Frame rates tend to snap to values of 30/N, where N is a positive
+ integer, i.e. 30 FPS, 15 FPS, 10, 7.5, 6. And the 'snapped' frame rate
+ is rounded down from what it would normally be.
+
+ So if we set animationTimeInterval to 1/120 instead of 1/30, frame rates
+ become values of 60/N, 120/N, or 240/N, with coarser or finer frame rate
+ steps for higher or lower animation time intervals respectively.
