60FPS appears in slow motion?

The Title says it all,

When I build to iOS, My FPS counter reflects that I am running at 60FPS,
BUT… the game seems to be running in slow motion, but the timescale is set to 1.

Does anyone have an idea as to what might be the problem?

  • My Fixed Timestep & Max allowed Timestep are both set to 0.016666,
  • I have also set my target Farmerate to 60FPS
  • VSYNC is OFF

Running this on my iPad Air

Anyone?

Guess I’m just gonna have to keep bumping this.

Sounds like you haven’t bothered to use Time.deltaTime. That’s not optional. If you don’t know what it is, you should peruse the Learn section in this site and generally look up framerate independent movement. In short, any movement you do outside of physics engine should be compensated by the delta of the time since last frame.

Here’s what’s happening. On desktop you have vsync off, but iOS enforces vsync on. Apple wants it on, so it’s on.

This of course caps you to 60fps, but desktop wasn’t running at 60fps but far higher :slight_smile: So learn delta time.

So why is it that the exact same project set up the exact same way in Unity 4.5.5
runs silky smooth?
Also, when VSYNC is enabled it yields the same result.
Any more ideas?

Have you multiplied any movement by delta time, yes or no?

It seems that when I changed my Graphics API to Open GL ES 2.0 everything got fixed.
It seems that Metal and Automatic API’s aren’t quite iOS friendly just yet.

Im having the same goddamn issue in my game…

My movements are in FixedUpdate using forces. From my understanding you don’t need to multiply by time.fixeddeltatime in FixedUpdate.

My game is in slow motion on iPad, but good on android and editor.
I’m gonna try your solution to force open gl es 2.0 and cross my fingers really really hard.

My game is VERY VERY LIGHTWEIGHT and SIMPLE. I’ve posted my issue in the iOS and physics forum sections and in unity answers and have gotten ZERO HELP.

I only found this thread after trying different terms in google search and finally stumbling here after several days of fruitless searching…

Just installed 5.3.4f1, gonna see if it’ll work without changing anything and go from there.

I figured out my issue,
