Hello, I've been optimising my game and yes FPS is always 60.
I've been testing the FPS/CPU/GPU/Renderer etc on mobile phones...
Unfortunately, there's some stuttering that occurs every now and then (only on Android) which might be coming from the Android web view. I doubt that can be fixed...
But overall I'm making sure once my game is completed, everyone can play it even if they have old smartphones.
So thank you, that gave me some motivation, hehe
