FPS

[Ctem]

Hello everyone. I'm developing a game on pixi. Faced with such a problem. When you start the game on the iphone in power saving mode, fps drops. I tried to track this to change the speed variable, but the game is still getting slower. Maybe I'm doing something wrong. Please tell me how to solve this problem?

 

   
   app.ticker.maxFPS = 60;

        app.ticker.add((time) =>
        {
            game.update();
          
             if(time.deltaMS > 33) {
                 game.counter = 2;
             }
             if(time.deltaMS < 25) {
                 game.counter = 1;
             }
        });
