In Topic: Diff between clover's nvidiaweb & nvidia pref?

15 October 2017 - 10:19 AM

A must for working Web driver is the NVRAM key  nvda_drv=1.

(you can look : nvram -p )

Doenst matter how this key comes into your nvram, but it must be present and set to 1 for working webdrivers.

I think the clover config nvidiaweb does handle / set this NVRAM key at boot time. (since the boot flag nv... is useless for Sierra+)

If you set nvram key by the nvidia prefpane or by hand: sudo nvram  nvda_drv=1 but disable clover nvidiaweb, the clover may overwrite the key with =0.

So both must be enabled.

PS:  Webdrivers not loaded

It may happen that you enable Clover webdriver but, because your NVRAM isnt working (depend on Mainboard, some need EmiEfi...efi, i not with GA Z 77) the webdriver

is not loaded!!! In this case, you enabled webdriver in clover, check if the nvram key really set and set to =1. ( nvram -p).

Other problems can be,

- nvram is set right, but webdriver isnt for used OS X build version (webdriver checks OS X build version) = Webdriver not loaded.

- nvram is OK, also webdriver build is OK, but kernelcache old (not updated = old webdriver version) OR some nv kexts have wrong owner(permissions) = Webdriver not loaded

- all OK, but on High Sierra - problems with HS new kext  allow security : web drivers not loaded if you installed them with SIP disabled 

- last but not least : all OK, but your SMBIOS (Mac Modell) is problematic for Nvidia gpu = use LILU + NVGraphicsFixup , if use both lastest (1.20) version - you MUST delete NVWebDriverLibValFix.kext if you used it before!!!! in /L/E & kernelcache update  - otherwise reboots.

I use older 4222 and see  (using -v) that always uses an boot arg slide=0 is used. But all working.

That slide=0 is not in set as boot arg in config.plist. (And is not  listet in nvram after boot)

Where does this boot arg slide=0 come from? Does Clover add this for boottime and then delete it from nvram?

??? What are you talking about slow 1080TI? Will for sure run much faster than 970!!! You can find Luxmark or many other (OS X) Benchvalues showing that. Or check barefeat site with his real world GPU reviews.


PS: Your GTX 970 would be at least 40% slower than shown GTX 980TI value!! So 1080TI is much faster than GTX 970 - always, doenst matter CUDA, OpenCL or Metal

Finder is still laggy, windowserver high cpu when scrolling over content. Metal 2 not so good nvidia :)

Are you sure Webdriver loaded ? High CPU means often no acceleration = laggy Windowserver (window move, scrolling laggy) because CPU must work much.

I am on GT 1030  and there is no such problem.

If you have probs :

First check if your NVRAM has really nvda_drv=1 key!!!!! 

nvram -p shows that.

If no such nvram key at boot time the webdriver will never loaded l!

The old way for nvda_drv=1 as an kernel boot flag does nothing - you can remove it.

If yo get  nvda_drv=1 shown by nvram -p  (after you set it by sudo nvram  nvda_drv=1 or used the Webdriver menue to set it from OSX default to Web)


If again no webdriver loaded even your nvram was OK before reboot) :

Then check  nvram -p  again - if no  nvda_drv=1 then your Mainboard didnt save the NVRAM and you need that emu...efi driver to emulate working NVRAM.
