I still can't seem to get my head around dt. I have a physics object that is set to frame rate independent and a timer that adds up in real time milliseconds.
Play it on my pc = fine
Play it on my mobile device, and the time counts as normal in real time, but my physics object moves slowly.
I also notice slowdown when additional sprites overwhelm. The drop from 60 to 30 can be disorienting. If I felt my game worked fine at 30fps, I'd like to limit it.
A game recently came out on pc. Naruto full burst. It's fixed at 30 fps, and some people aren't happy, but I think it runs great. Sure it may run better at 60, but I don't need any faster.
I feel my mobile game would benefit greatly from a locked 30fps, but Ashley is the genius here, not me.
