    Hi guys,

    Just to give you a feedback.
    Under DP4 i had tons of problems like black screen, sleep not working and 5 to 8 kernel panic everyday.
    I updated from DP4 to GM and some of those problems were persistants.
    I had to format and clean install GM.

    General feedback: ML is laggy with the integrated graphics, smooth with the nVidia.
    No PowerNap available, probably waiting on a FW update.
    General usage is good, i HIGHLY recommend you to clean install if you have a MBPr.

    Here's my experience on the GM:

    Safari: Very good, no lag and scrolling is very fast (don't use Facebook so can't test that one).

    Switching from Desktop to Desktop, or full-screen app-full-screen app, etc.: Very good and smooth no lag or jerkiness.

    Mission Control: Laggy and stutters, rather disappointing (smooth on dGPU).

    Launchpad: Smooth with no issues.

    TextEdit: When you have a few pages of content or some tables, scrolling and what's displayed is very choppy and it takes a lot of time to redraw everything. Performance is very bad, though vastly improved from Lion. Sucks on both integrated and discrete GPU.

    If you'd like me to check other UIs let me know.

    Update: iphoto is very good, and automatically enables the dGPU upon launch.

    Test conducted on Best for Retina setting.

    Mine seems fine, overall an improvement at the moment :)

    I think if you do just upgrade it doesn't override graphics drivers? Possible cause

    Unlikely, it unpacks all the files it needs for the upgrade. Do you have some proof/evidence?

    No just conjecture, why are some people having flawless upgrades?

    Just depends on how much cruft you have in your system. Older OS's didn't clean up as nicely as the later ones do. So if you have been updating since Jaguar, there may be some legacy code causing issues.

    Apple actually does a great job of segregating the OS from apps and user files. Only a few apps cause problems, like Cisco VPN, which installed some bits in the OS directories. That was a few years ago, so maybe even they have cleaned up their code since.

    I really have a clean filesystem, using appzapper to remove prefs etc, however, i upgraded to DP4 and had 80 gigs free, after formating and importing "by hand" all my docs and apps (without the prefs and folders of the library) I had 100 gigs free.
    I think that games and some apps like adobe products leaves a LOT of files and caches even if you use app zapper like programs or uninstallers.

    I have a rMBP and I installed Mt. Lion on a separate partition. Now, to be fair, I didn't notice any issues on Lion but when I run ML I feel like I just bought Snow Leopard again. It's fast, responsive, and makes me love Apple so much.

    I just installed ML on my rMBP and its super fast and super responsive. Huge improvement over Lion.
