    EDIT:
    Seems to be solved since B25

    Hello!

    It takes Unity 5.4.0B24 about 2 minutes to change the quality settings for iOS of a normal map after I hit "Apply".

    Greetings,

    If that's a big map (2k?) I'd say that's normal for the pvrtool. (it's recompressing when you change stuff)

    Yes, it is 2048px. Only takes about 4 seconds when recompressing for Mac / Windows / Linux, though.
    I've never experienced such a slow compression before, no matter what platform I was targeting.
    It does, however, reduce its size from 5.3MB (compressed for Mac / Windows / Linux) to 2.7MB (compressed for iOS).
    PVRTC isn't a new way of compressing, though, is it? If it was, that would explain why I didn't notice this before (have been using 5.2.2 before 5.4.0B).

    DXT compression is much, MUCH faster than pvr and astc.

    Did the compression time change compared to 5.3?

    Can't tell you about 5.3, but I have been developing for iOS in 5.2.2 before without compression taking that long.
    I will take a look at 5.2.2 again and see if I can figure out what's going on.

    EDIT:
    No, this is indeed a new problem. Takes about 15 seconds to compress the exact same texture to 2048px for iOS, PVRTC, normal map in 5.2.2.
