About:
New Nvidia Retail drivers have been released today. It introduces a new Preference Pane under System Preferences that allows you to enable the Nvidia Web Driver or OS X Default Driver The new drivers require information to be written to the NVram. Without this you will not be able to.  Meklort, who developed the NVram Module that we currently use, assisted me in understanding why the NVram information showed up on some systems and not others. If you are using my Recovery Partition And Enable All Features Of iCloud and iMessages fix you must remove nvram.log from /var/log/ before you can begin.
If you plan to enable ECC, for a Nvidia card that support this feature, you must add the slot identification edit in your DSDT or the option to enable ECC on that card will not be available.
Accreditation:
Meklort for NVram Module and boot.plist Flag

There is some advantage to use the new drivers?
Yes, if you are having issues with the current one. These basically remove the bugs from the current ones.
This Works on Mavericks ?
My video card is GT9500
No
It says this computer is not compatible with web driver.
Must be using Mac Pro SMBIOS.

You don’t

These web drivers totally SUCK for my GTX 5xx Firmi cards. They drop Luxmark 2.0 OpenCL performance by a whopping 35%!!!!!! GTX 580 Classified 3GB drops from 1430 to 1050. GTX 570 HD 2.5GB drops from 1101 to 844. I switched back immediately. I wonder if 6xx Kelper users are seeing a performance increase or decrease? I also wonder if this is nVidia trying to cripple/throttle the 5xx cards to sell new ones. I guess the next update will give more insight about that.
Remove AGPM.kext as the new drivers provide there own powermanagement. There is no longer a need to edit the Apple kext.
Deleting AppleGraphicsPowerManagement.kext from S/L/E does not change or improve performance for me when the web driver is selected.
Working fine for my GTX 580.
________________________________
Do you get Identical Luxmark2.0 scores when you switch back and forth from the web and stock 10.8.3 drivers? Also, are you sure you are actually using the web driver? I had to update chameleon before I could get the actual switch to take effect.
Sorry… of couse you are sure. LOL
Seems to be fine for me… I really like the native PM for the GPU now. 🙂 Could it be they just fixed the bug like the GTX 6xx cards had in score reporting prior to 10.8.3? Could be related? If I did not have fermi lock on 10.8.4 I would test and see.
I think it is the reporting error. Shows 16 & 15 compute units with the web driver and 60 & 64 compute units with the stock driver.
I get a strange thing, if I want to use web nvidia driver I have to install chameleon bootloader and works fine but stops working Tuxera ntfs , and install chimera bootloader if I can not use web nvidia driver but if it works Tuxera ntfs.
why is that?
Not sure… bug with the driver?
Driver ? bootloader is the problem , chamaleon no work tuxera ntfs and chimera work fine , is strange…….. driver with chameleon work fine but with chimero no work ……
Sounds more like a Nvram issue then a boot loader issue. Chimera is the same a cham. and Chimera breaks NVRAM. Install by hand the latest cham, release and only use the boot flag and remover the Nvram module and test.
where I can get the last?
The link in the guide.
ok thanks , only reemplace nvram in extra/modules ?
Remove it.
I did what you said and it seems to work all right, you’re a machine, thanks 🙂
OK, it was a NVRam bug. You can put the module back now…
Ouch I get the error, “This computer is not compatible with the NVIDIA web driver.” I have an Asus P8Z77-V Motherboard with a i7-3770K CPU and 32 gigs of RAM, plus a newer EVGA GTX-650 video card. What does the damn driver want?
Maybe its because the display adapter is listed as unknown?
Alone and confused!!!!!

Change SMBIOS to Mac Pro 3,1 and reboot. Then try. 10.8.4 is out and these drivers are defunct.
Thanks RampageDev, will try after my copy operation is over……..
or
Im on 10.8.4 already should I just wait for newer drivers?
Just wait now for the new retail release. Nothing wrong with the new drivers. Apple puts the fixes the retail drivers have in the next release so these noobs who think they are better drivers are miss lead. On IM you see noobs flipping out as they can not use the Retail drivers on 10.8.4…
Thanks for the feedback RampageDev. I can wait. Just wish 10.8.4 hadn’t killed my audio drivers. Damn Apple and their infernal updates.
Spazz0ut
Just reinstall the patched AppleHDA you were using before.
________________________________
No joy there Rampagedev… I get an error about the kext not installing no matter what I do. Even the TonyMac Multibeast errors when I try to install the ACL driver. I don’t have a patched AppleHDA.kext for my board as far as I know. Multibeast used to work. Im still kind of a mackintosh newbie……
Sounds like your SMBIOS is not a mac pro. Install has nothing to do with the mackintosh side other then using a SMBIOS of a Mac Pro.
Wow are you good. I just checked with chameleon wizard and I had no SMBIOS file. I set it to Mac Pro 3.1 and will try the install again. YOU RAWK!!!! 😎
Enjoy.
Got it sorted. Was as easy as removing the HDAxxxxx.kext from /S/L/E and reinstalling ACL892.kext from Multibeast. Install indicates failure but on reboot sound works. Go figure. Thanks again for your AWESOME support Rampie!
I still can’t get audio to install. All attempts result in installation failure.
😦
Andrew , many thanks for your help …you are a great friend.
Ps: I also resolved to overclock, I had a wrong setting in the bios, and now my score ‘of 22000 points
Good. Your were driving me nuts…
Lol , You’re a funny man….
sorry for driving you nutZ! but it is s shirt drive after all!
😛
He drives many of us nuts…
Dude Help!
Im on Z77N-WiFi and 3.4 GHz Intel Core i5 running NVIDIA GeForce GTX 660 SC 2047 MB
All was great until I was tempted to install 313.01.02f01.
Now I managed to make the Nvidia driver default but the UI became flaky. i.e. I use dock autohiding so now its like 2 stage – one dock shows then followed by the proper one or empty trash popup shows that slow animation – all was excellent before.
Uninstalled the driver completely and it was even worse… so back on latest nvidia..
Updated Chimera but still the UI has definitely visible slowness..
Dude I have seem to find the weirdest fix for this of all…

Re: Mountain Lion choppy animations
Nov 11, 2012 4:15 PM (in response to MartinDimov)
The following weird steps solved my problem:
1. Repair disk permission in Disk Utility
2. Restart
3. Launch AutoCAD 2013
4. Close AutoCAD 2013
5. Fixed
Finally, I got rid of those headache choppy animations without reinstalling everything from scratch. Hope they can help you too.
This might be helpful to someone.. and thanks for your great work you are doing here!
Update the bootloader to trunk.
Hello Rampagedev!
If possible I would appreciate it very much if you could help me.
I have an ASUS GTX560Ti DirectCU II card which is factory overclocked (device ID 10de1200) and I get everything working just fine on my computer with it. Just that no matter what I do with regards to editing the AGPM.kext it does not seem to throttle the GPU… It looks as if runs full speed always with fan speed increasing and the same for heat…. I would really appreciate your help with this. Machine identifies as MacPro3,1/5,1 (I’ve also tried iMac 12,1 for the AGPM.kext.
Managed to get the Web Drivers running also (MacPro3,1 system) but still NO control over temperature/performance/fan noise…did delete the AGPM.kext as you suggested but no difference.Doesn’t seem the Web Driver helps with that at all….
mr_hackintosh
Editing that kext is no longer needed as the Native drivers handle it and not the AGPM.kext anymore…
Okay I got GPU throttling/fan control working by using the default OSX Nvidia drivers under an iMac12,1 system profile and making the edits to AGPM.kext suggested here
http://blog.thireus.com/guide-hackintosh-install-macos-mountain-lion-10-8-on-asus-sabertooth-p67-in-3-steps
Now my GTX560Ti card idles at 45 degrees celsius and lowers/increases the fan rpm according to load. When I tried this with the Nvidia Web drivers under MacPro3,1, 4,1 and 5,1 system profile it did not work. GPU running very warm and fan being noisy…
I have an unrelated question though: When I go into About This Mac / System Report / and try looking under Software / Extensions all I get is “There was an error while gathering this information.” would you happen to have any idea what is wrong? It works fine for me to do the same thing on an older hackintosh install (ML 10.8.2) that I have on another computer….
//Mr_Hackintosh
Great work.
8400GS here with iMac9,1 SMBIOS. It says that my computer it’s not compatible.
There are any improvements over the default OS X’s driver (in my case)?
Change the SMBIOS to Mac Pro 3,1 and install the drivers. Some users may see improvements.
is it okay to install the Kext on 10.9 mavericks?
Do I talk about 10.9 at all… think about it 😉
