Missing all the "DAE Playback Buffer Size" settings in Pro Tools 11 & 10?

[music.mak]

Hello everyone.

I have a problem and couldn't find an answer or a solution by Googling or so...
The problem is:

- I'm using Pro Tools 10 & 11 with the "MBox Pro 3rd Gen", and I don't have "DAE Playback Buffer Size" settings, which is normally under the Hardware Buffer Size & Delay Compensation settings!

Please, help me to find out what's going on... Is it normal and some specific versions are like this (as mine), or is this a problem?

Here is the screenshots of my Pro Tools 10 and 11:

Those things don't exist in PT11. The engine has been rewritten and those things are optimized by the software.
