What's the status of simd in mobile game developing now,is it a common practice or a must,as far as I know,NEON is the way to go for mobile platforms,right?How well do mobiles support this techniques nowadays?thanks.

Definitely use NEON if you're doing something that benefits from it, like matrix/vector math. I believe almost all mobile platforms support it.

@bioglaze Glad to know it's widely supported,thanks.
