11.4 Big Sur / Nvidia GTX 780Ti

[bobenia]

Hi everyone,
after successfully installed Opencore BigSur 11.4 I have issues with display driver for my GTX 780 Ti.
Any idea how to make it working. Followed Dortania's guide and it's supported graphic card.

Do I need to install web driver or just add whatever green kext.
If I try to install WebDriver I got error it's not supported on this OSX version.
driver:

Quadro & GeForce macOS Driver Release 387.10.10.10.25.156 | 387.10.10.10.25.156 | | NVIDIA

Download the English (US) Quadro & GeForce macOS Driver Release 387.10.10.10.25.156 for systems. Released 2018.1.24

Please help !

No the Web drivers won't work in 11.4. For Nvidia you may need to add nvda_drv_vrl=1 as boot-args though.

User interface is very laggy, no transparency at all etc...like there is no any display driver ...
It's an EVGA GTX 780 Ti

Okay, that means no acceleration from hardware.

What does System Report (About This Mac etc) say about the GPU?

Okay, that's useful.

It actually looks as though you might have a GTX 980 GPU and not a GTX 780. (At least that is what the Device ID is for).

Sadly the GTX 980 is not supported by macOS Big Sur.

The latest macOS that supports it is High Sierra and with the Nvidia Web-Drivers.

It's probably a 980 Ti so it only works up through High Sierra with the correct web drivers installed.
The OP can always run GPU-Z in Windows to get the exact specs of the card.

))) it's GTX 980ti's
Jesus, I forgot completely..originaly PC was bought with 780ti and later replaced with 980Ti few years back and I completely forgot that.
So with 980Ti no way to make it working under Bug Sur?
I have somewhere archived older 780Ti, I'll try put it back and check with them...

holy ...
