UI Bad performance on IPAD 3

Unity Engine
1

Hi,

has anyone noticed really really bad performance with UIs on an IPAD 3 ? Or another high resolution device ?

My game is fluid and ok on every devices I’ve tested but incredibly bad on ipad 3.
I suppose it’s somehow related to the resolution (1536 * 2048, retina shit), but still I have no idea why my menus and UIs are “laggy”.
This is very weird as it’s only about menus, the game (3D runner) is running fine. But when a menu pops, when a raycast is launched or a button pressed, it’s just incredibly “late” or “stuttered”.

My tests so far :

Samsung galaxy S4 - S5 - S6 : OK
Iphone 4S - 5S - 5C - 6 : OK
IPad mini / IPad 2 : OK
IPad 3 : SHIT :frowning:

Anyone ?

Thanks !

Can you provide more information, which version of Unity are you using?
There been other reports about issues on specific Apple devices.

Are you using lists of prefabs ?

You might need to optimize the UI to only show whats needed , Check if you are running the game in the background as well ? I was thinking it could be a CPU or fill rate issue since iPad 3 isnt that powerul - Maybe you want to render the game to a render texture hide the entire game and reenable that again to make sure that as little is going on in the background as possible ?

Cheers!
