AFAIK FCP fires up my GTX-670 (PC) 4GB memory and processing power when rendering a sequence alongside the CPU power.

Compressor uses all my 12 CPU cores.

Could you give me a clue, how can you tell from those pictures that FCP7 has learned to use GPU's computational power to accelerate rendering? You can't tell that from fcp using GPU's memory...
 
I have just installed the latest Web Driver in OS X 10.11.5 and the version reads "346.03.10f02." Also my Cuda Driver 7.5.29 shows "GPU Driver Version: 10.11.10 (346.03.10.f02). I don't know what these tell me but the Web Driver seems to have been updated from 346.03.10f01.

In this screen cap you can see that the CPU is only just using 10,6% and the GPU is rendering @36.1 FPS using memory and process usage of the GPU GTX-670. This was always my understanding how FCP7 is using the GTX-670 for rendering a sequence, of course you may correct me if I'm totally concluding in te wrong direction.

I think that 36.1 FPS is what's happening on your screen now, not the frame rendering in FCP 7.

If you keep moving you mouse pointer over the iStat windows, you should able to easily make that number stick at around 60, regardless if FCP 7 is running or not.

As you can see, I can make the FPS jump from 3.5 to 60.4 by just moving my mouse around.

I'm not only referring to the memory, but specially to the proces!

I agree that the processor usage may shows that FCP 7 is using the GPU for something. I just want to point out that 36.1 should be irrelevant.

Just some sharing, when FCP X rendering 4K video on my Mac, iStat looks like this.

^^^^ Oke I see what you mean, perhaps I did have made some wrong assumptions here on the working of FCP7 and the use of the GTX for render jobs. Will have to do some homework then! ;-)

I was actually responding to the guy who said 680 was fastest card supported in default OSX drivers.

Beauty of 780 is you don't have to mess with Web Drivers if you don't want.

Unless Apple wakes up and puts Pascal in 7,1 I think we can count on them NOT being in default drivers.

And 1080 will be faster, esp for CUDA/OpenCl

thanks for that tip did not know the GTX 780 worked by default with the osx drivers, I like the GTX 770 as it seems to run ok from internal power (about 10% faster than 680 and a lot cheaper on ebay).
I dont need a lot of GPU power at the mo for what i do, just want more than i have now & like the option of the default drivers i had a few crashes with the nvidia ones.

edit FC7 has some GPU powered effects
 
^^^^Well, the GTX 780 does run on Apple drivers IF if it has the GX 110A chip. Late GTX 780s with the GK110B version of the chip will not run in accelerated mode using OS X Drivers. I have the GK110A, so I'm OK. But I use the Web Drivers.

But, I'm seriously thinking of jumping to the GTX 1080 when the Web Drivers contain the Pascal code.

Hi, I'm very sorry if this has been asked already, I've tried to look through this thread as much as possible for my answer but don't see it.

I have a MacPro 4,1 with a GTX 960 and Web Driver 10.11.5. Everything was working great until I updated El Capitan prior to installing the 10.11.6. Now I get black screens and can't navigate to install the Web Driver update.

I used Target Disk Mode with a Macbook Pro and am able to see my Mac Pro's drives, but I don't know how to install the Web Driver update while in TDM. Any help would be greatly appreciated and apologies if this is redundant to the thread.

^^^^Nvidia changes the Web Driver with every point release of an Apple OS. Therefore the 10.11.5 driver (346.03.10f02) will not work with the Beta 10.11.6. Nvidia does release Beta drivers however, and there is one for 10.11.6, it is here:

http://us.download.nvidia.com/wanl9YNPeTLf4ztbBsDkiMXsE4tbtMGp/WebDriver-346.03.15b01.pkg

And yes, your answer is contained in this thread

Yes I realize that's the file, but I don't know how to install it in TDM. Do you know where in the thread this is answered?
 
^^^^If it's running on the Apple Driver, it should work with a GTX 960, but without acceleration.

Try this:

1. Boot your Mac Pro in to Target Disk Mode.
2. Connect Mac Pro to your MacBook Pro and boot your MacBook Pro from the Target Disk Mode.
3. Install the correct Nvidia web drivers.

Be sure not to reset the PRAM on the Mac Pro since it should still have the "nvda_drv=1" boot-arg.

Thanks for the response. Part 3 is what I'm having trouble with. I don't understand how I can install the web drivers to the startup disk in my Mac Pro via TDM. When I open the Web Driver on the MBP, it tells me the Web Driver's incompatible and I'm never given a chance to select the Mac Pro's startup disk
 
Ah... I see... I guess the Nvidia web drivers are looking for an Nvidia GPU which your MacBook Pro doesn't have. The only thing I can think of would be to try and use an app like Pacifist to extract the driver files and install them manually...

* Disclaimer: I've never tried this and it may not work at all.

See #25 in the FAQ.

The FAQ says the hardware check was removed, so I don't know why you are still experiencing it. In any case, the instructions for disabling the hardware check are still there in the FAQ.
 
or if you still have your old mac gpu (or pre gtx 770 pc gpu) you can just stick that in do the update then put you new gpu back in.

GK110B is fine with stock drivers, too (got one in my Hack). Only 780ti needs WebDrivers.
