    Anybody else with a Nvidia 560ti started getting freezes with the latest driver updates/10.8.3?

    First noticed when upgrading to 10.8.3. OS X will boot fine. After leaving the OS idle for a small amount of time or whilst doing no graphics intensive work the computer will lock up but the mouse will still be moveable and I can still hear things like volume changes working.

    I have also tried using the latest Nvidia drivers on 10.8.2 and the same effects are replicated after 10.8.2 has worked fine for moths with the Apple provided drivers.

    Kinda bummed at this seeing as my system has been running pretty smooth for quite some time now.

    UPDATE With Fix/Work around
    After testing multiple things we have come to the conclusion that while editing your AGPM kext did drastically reduce the number of freezes this is not the main cause of the problem. Another forum member by the name of dan542 has came up with a great solution to the problem. Seeing as editing the AGPM kext only made the freezes less frequent we narrowed it down to a driver problem managing processes on the GPU. By using the app he created (Which I have attached below) it uses one or more channels while your computer is on in the background, after testing so far it seems to "fix" these freezes.

    Download freeze fix app
    I have also uploaded the app again here as I know if the file gets moved in his dropbox it will break the above link.

    To make using this app most efficient add it to your login items under System Preferences > Users & Groups > Login Items
    Making sure you:
    1. Don't check for the app to be hidden when launching (Doing so will cause the app to not run correctly and you will continue to get freezes).
    2. Add the program to the login items of any other users that use the computer as it will not open for other users if not set.

    Again credit for making the app goes to dan542

    ----------------------------------------------------------------------------------------------

    Instructions for Editing AGPM Kext
    While we are now using a different solution to the freezing problem I personally found editing my DSDT slowed down the freezes and made my graphics in total a bit more stable so I have left the instruction below. Thanks goes to dan542 for this great simple guide on the process as some articles online didn't explain the whole process very well :)

    Small update. This is my console log as the crash happens on 10.8.2. with the latest Nvidia drivers.

    Now going to update to 10.8.3 and see if the same error is reported with the Apple supplied drivers.

    I didn't had any freeze on 10.8.2. I always had used the apple drivers.

    Now, it's very annoying this freeze. It usually happens when I close a tab or a program.

    Maybe we need to edit the AGPM kext to avoid a lower state for the card.

    Cheers!

    Yeah I never had any problems with the drivers Apple provided. That is with the latest Nvidia drivers. I am currently back on 10.8.3 and haven't had a freeze for about an hour now. This time I didn't bother with the OpenCL patch in multi-beast to see the effects. So far it seems that might be what caused the freezes but don't count me on that one as it's only been an hour ;)

    Ok nope scratch that just got replicated the crash in 10.8.3

    As you can see from the Console it's definitely a graphics problem with errors relating to a OpenGL timeout.

    Will it work?

    Cheers!

    I have the same issues with my GTX 550Ti. However I did not do the Combo update, I updated through Software Update. I am downloading and installing the Combo update now to see if this resolves the problem. Figured its worth a shot.

    Yeah I also used the combo update, fixed permissions then ran multi-beast for audio.

    Another thing to add I have also tonymac straight up say the mid rangle 500 series cards just simply don't have stability with the latest drivers and advises people to try and sell them for a 600 series card to avoid future problems but it's something i'd like to avoid if possible XD
