In the performance tips section, https://github.com/pixijs/pixi.js/wiki/v4-Performance-Tips, it mentions " On older devices use smaller low res textures "
How do you detect that in a mobile browser? Especially on iphone/ipad? The UA string identifies ipad/iphone but not the model numbers.
I would love to use 1/2 size textures on iphone5, but don't want to cripple the experience on iphone7 etc.
Thanks in advance.
