Game playing should have the same rate of motion as when played under Scratch 2
Actual Behavior
The game lags much more frequently when run under Scratch 3
Steps to Reproduce
Play this game through level 10. Since the amount of noticible lag in a game is subjective I’ve added some measurements that, for me at least, quantified what I felt as I played the game.
User cs1158230 reported in the forums that the lag in this project when run under Scratch 3 was "kinda bad". Because they only posted a link to a non-shared remix, I don't know who wrote the original project. Here's the post: https://scratch.mit.edu/discuss/topic/321471/
I modified the project by adding a frame rate calculation and a counter to show the number of one second intervals where the frame rate was less than 24. This is arbitrary but the lag in intervals with a frame rate less than 24 felt "kinda bad" to me (your mileage may vary).
I played the game through level 10:
Scratch 2.0 low frame rate count was 8 intervals
Scratch 3.0 low frame rate count was 30 intervals
