Installed nvidia web driver, still using osx driver?

[tomtom3456]

Hello

I am a little confused with the driver situation.
I have a NVIDIA GeForce GTX 760 2048MB graphicscard in my PC and I installed the nvidia webstart driver for the latest OSX El Capitan. The Nvidia entry in the System Preferences shows OS X Default Graphics Driver in use, when i change it to nvidia web driver i am asked for a reboot, after rebooting it shows the OSX driver again. Graphics seems to be accelerated but performance in diablo 3 for example is very poor.


What am I missing?

It will only say that you are using the web driver in the Nvidia Driver Manager if the boot flag nvda_drv=1 is being stored properly in your NVRAM.

Use this command in terminal to see if the flag is there:

sudo nvram boot-args

It will return any boot flags saved to the nvram. If it isn't there and you didn't add that flag to your config.plist then you might be using the default OS X drivers.​

To check if the web driver is the one being used regardless of what the Nvidia Driver Manager says use the command:

kextstat | grep nv

If the drivers listed from that output end in "Web" then you are using the web drivers.​

ncram boot-args returns an error:

nvram boot-args
nvram: Error getting variable - 'boot-args': (iokit/common) data was not found

kextstat show this

Ok so the nvram error means that you don't have any boot flags being stored and kextstat shows you are not using the web driver. You will need to add nvda_drv=1 to your config.plist.

If using Clover boot loader you can either use Clover Configurator (here) or you can add the boot flag to your config.plist here:

<key>Boot</key>
	<dict>
		<key>Arguments</key>
		<string>nvda_drv=1</string>
...

The Clover configurator does not work for me, does not recognise my efi partion, but nvm, i am comfortable with the command line and vim.

I found a config.plist on /dev/disk1s1 (OSX is on disk1s2, not the primary hdd), mounted it and in /EFI/CLOVER/config.plist i found this:

...
<key>Boot</key>
        <dict>
                <key>Arguments</key>
                <string>dart=0</string>
                <key>DefaultVolume</key>
                <string>MacOSX</string>
                <key>Legacy</key>
                <string>PBR</string>
....

Now my question is, how would i add a second Argument after the dart=0, is it simply <key> Arguments</key><string>dart=0, nvda_drv=1 </string> or do i add a second <string> below?

 

[slim.jim]

It would be <string>dart=0 nvda_drv=1</string>. No comma.

 

[tomtom3456]

sudo nvram boot-args
boot-args	nvda_drv=1

kextstat |grep nv

Am i good now?

Thanks for your help!

Yes you are using the web drivers now.

Thank you for referring me to this thread. After reviewing the comments, I'm a bit stuck on getting mine to work. This is the step where I'm halted. Being new to the Clover Configurator, I'm unsure where to place the code (assuming not terminal) in order to get my web drivers to run. Thank you.

My system is the same situation with boot-args. I as well get nvram boot-argsnvram: Error getting variable - 'boot-args': (iokit/common) data was not found
