FPS drop during computing

Hi @GianVal ,

the question is what kind of iteration is it - I think such behavior could be  normal if you do any iteration steps in nearly infinity loop.

So what you can do if the loop is doing some calculation which are not directly affecting widgets properties and display then you can try to call the calculation to second thread - e.g.

Another points is to call in each iteration the call

$scope.$applyAsync();

or to call each iteration as function with $timeout service with / or without delay

So for example you can try something like this:

let myDelayPerItterationCall = 100; //so 100 millisecond per call delay
for(let i=0; i< verylargeNumber; i++)
{
$timeout(()=>{ 
 myFunction1();
 ....
 myFunctionN();
 $scope.$applyAsync(); 
 }, myDelayPerItterationCall *i) //end timeout call
} //end for loope
