Solving NVIDIA Driver Install & Loading Problems

[grootbatavia]

The Intel 530 does 4K@60Hz just fine. I've tested the The Dell UP2715K in Windows using Intel 530. It works at 5K with dual DisplayPort (Clover boot screen is 1024x768) and 4K with single DisplayPort (Clover boot screen is same rez), both at 60Hz. In 5K with the Intel 530, I think there's a second small display added in Windows and Ubuntu. In Ubuntu, it shows as 848x480. Ubuntu doesn't have the 5K option for Intel 530; it only allows 4K.

FPS does not depend on VRAM. If a game can't put all it's textures on the GPU, then you'll see performance issues. GPUs draw one frame per 1/60th of a second, not 60 frames at a time so you shouldn't multiply VRAM by 60. Some games might triple buffer, so you could multiply by 3. Maybe add more for a z-buffer or other types of buffers. But definitely not 60 buffers. Nvidia's specs say the 960 can output 5120x3200 using two DisplayPort 1.2 cables.

What kind of cable are you using to plug the display into the 960? You should be using the Mini DisplayPort to DisplayPort cable that came with the monitor to get 4K@60Hz. Make sure you're using the Nvidia Web drivers.

Hi Joe,

Was using dual DP 1.2 cables, but that got me stuck at 2560. Now I've switched to mini dp to dp and I have 3840! Thanks for that. Still not as much as I would like, but a notable resolution boost versus the initial results. Somehow the native setting seems to be 1920x1080 (scaled) resolution, but that's easy enough to fix using the display properties. After all, the whole point of high resolution for me, besides editing photographs is creating desktop space to run multiple applications on the same screen. Thanks so far, this makes the rig much more useful and sort of makes switching between windows and my hackintosh install a thing of the past. Now on to get full 5K!

nvda_drv=1 can be in config.plist or in the NVRAM or both. Clover changes config.plist. The NVIDIA Driver Manager preferences panel changes NVRAM. To see NVRAM in Mac OS X, type "nvram -p" in Terminal.app and look at the output for "boot-args".

OK, so there is nothing I should do about it, right?
Thanks again.

Right. If you have working NVRAM, then the NVIDIA preferences panel will tell you that you're using the web drivers. If you're NVRAM is not working, then NVIDIA preferences panel will be incorrect.

To be sure, the following command will tell you which driver you're using.

kextstat | grep web

The result should look like this (web means the web driver is being used):

  129    2 0xffffff7f8113b000 0x2e0000   0x2e0000   com.nvidia.web.NVDAResmanWeb (10.1.1) 5C094812-86E1-35B5-9B9F-AFD29D97CEC3 <128 125 115 12 7 5 4 3 1>

  130    0 0xffffff7f8142a000 0x1ae000   0x1ae000   com.nvidia.web.NVDAGK100HalWeb (10.1.1) EFB29A28-D743-3BE4-8579-7D31CD0444FF <129 12 4 3>

Should use: sudo kextstat | grep nv

If the web drivers are running then you will get an error if you use web instead of nv

grep web produces no error when the web drivers are installed or not. It will produce no results if the web drivers are not installed.

grep nv also returns a result for com.nvidia.CUDA which is not part of the web drivers.

I could at last do some tests before putting my new computer to production. Everything is pretty fast and smooth. Starting up though is extremely slow with a black screen most of the time. Shutting down ditto.
My different image applications like Adobe Bridge, Affinity Photo, Keynote work perfectly without the lags that were very annoying with my Mac Mini.
Yet I think I took a subscription with troubles because the application I use most, DxO Optics Pro 10, displays terrible artifacts when I play with sliders.
I read the about the issue of artifacts with GPUs often.
In which forum should I ask my question? Is there any hope to solve the problem?
Is it the GPU, the drivers, the application itself, OS X?
It's workable but it puts into question the whole purpose of my build. It's the application I hoped the most benefits for.

This isn't really the thread to ask this question. I would make your own thread to ask your questions and hopefully someone uses similar hardware and software.

OK.
FYI: I solved the issue (hopefully). I was running DOP 10 and had planned upgrading to the recently released DOP 11 version in a month or two only. I downloaded the trial version and it's perfectly clean.
I suppose the old version (10) was developed before the release of GTX 950 and hence was not fully compatible.
Thanks again, folks.

Using that Terminal command, I get the attached display. Is this correct for the nVidia web driver? Also if I look at the "Graphics/Display" item in System Report, I see the active nVidia extensions. Are they correct to use the nVidia web driver? My nVidia driver manager preferences display shows the OS X drivers and the "Restart" button is always dimmed.

Yes you are using the web drivers.
