does anybody know what it is? 32 bytes? 64 bytes to match armv7? just wondering, so to try and match my vertex layout size.
That’s not public information, I’m afraid and varies between platforms.
Try to ensure your vertex size is a multiple of 4 and as small as possible - greater powers of two may be better, but it depends on the platform i.e. 32 may be better than 28, but 24 may be better than 32 etc.
