Hello.

I have a 12GB GTX Titan X installed in my Mackintosh running OpenCore 0.6.8. I am using Nvidia drivers: 387.10.10.10.40.140 and my High Sierra install is 10.13.6 (17G14042). I'm pretty sure that web driver is the correct one based on my High Sierra install.

For the life of me, I cannot get the graphics to work correctly. My "About This Mac" keeps showing Graphics: NVIDIA Chip Model 8 MB. The screen tears constantly, I can't play any video or anything else.

I've tried everything I can think of. Reset the NVRAM many times, I've double checked everything I can think of and gone thru my config.plist so many times. It all worked fine under Clover. OpenCore is definitely getting the best of me. Everything else works very well, including sleep, audio, etc. Any help would be greatly appreciated.

Thank you in advance.
