Re: [elm-discuss] How to render at a lower fps in 0.17?

[Peter Damoc]

Oh well, you can always use an accumulator like `timeSinceLastFrame` and
check it against some timePerFrame that you want.
If the time is greater than timePerFrame, reset to
(timeSinceLastFrame-timePerFrame) and update the module state. If not, just
add the delta to timeSinceLastFrame.

You won't get the precision of a specific FPS but you should get a
consistent behavior.

You can use Time.every to get deltas if you store the old one in the model. The 
best use, other than the actual time, is things you want to happen periodically 
but the exact millisecond doesn't matter. If you're doing animation, I'll echo 
Peter: what's wrong with animating on the browser's exact frames?

[elm-discuss] How to render at a lower fps in 0.17?

[Wil C]

I've made the switch to 0.17, and I've also followed along with the mario 
example . 
I can see how to get the delta, but it's locked in at around 60 fps with a 
subscription like "AnimationFrame.diffs Tick". How do I subscribe to 
AnimationFrame.diff with a lower framerate? It doesn't looks like I can use 
Time.every.
