so i just found the issue, its not about optimizing. its about the fps. i build this game on my pc with 144hz monitor. and whenever i run the game on 60hz device, it run slow. ive searched something about fps and slow speed, people recommend to use dt.i havent tried it, BUT i tried to delete all my event (which i assume is the same cause theres no event) but it still run slow in 60fps
