ok im creating a game but it uses too much cpu but it doesn’t uses too much memory. the cpu does increase and decrease. i have too many timers in my game, i kill the timer when i don’t use it any more so that should cause a problem but what i think that causes the problem is there is too many messages in my message qeue. i have new laptop it is 5 months old and it has a high cpu. it uses about 40% of my cpu. is there way to reduce it because when it gets to 40% the game slows down.
here is my code
