El Capitan - NVIDIA GTX970 - Operating only 35%

[RallyVermont]

Hey guys,

Recently updated to El Capitan with a GTX970 from Mavericks with a GTX760. Mevericks was very stable, glitch free and speedy for Premiere Pro. Lightroom no longer supported the 760 and was deathly slow. So here I am with a 970 and El Capitan.

To my surprise render/export times with the 970 is about 25% slower In Premiere Pro CC. I'm running the XRG monitor and see that a max 35% is being requested and or used by the GPU.

I have the web drivers installed and Cuda loaded. At this rate I'm able to use Lightroom faster however Premiere Pro has greatly slowed down since the Mavericks/GTX760 install.

Bad card? Improper drivers? Missing a key component of adjusting GPU usage?

I've also noticed that 0mb ram is visible when is system overview - related issue?

Any help would be appreciated!

Disable Inject/Nvidia for full VRAM. Not sure if this will fix your performance issues, but it's worth a try.

At this time I don't believe it's been injected via Multibeast. Do I need to manually disable? It's very odd. Using programs like Lightroom, I can tell the GPU is being used as it's much faster. But the GPU activity just stays at 25% and doesn't deviate. Im not sure of any way to have the GPU pick up more of the work.

You can see the 970 is recognized by the NVIDIA driver manager.

The only way to get that string there (-> "EVGA GeForce GTX 970 0 MB") is injection, either by using Clover or by making a custom SSDT. The Nvidia drivers would otherwise state NVIDIA GeForce GTX 970 with correct amount of VRAM.

Besides that, your performance issues might be caused by a bottleneck somewhere else. If your GPU is performing fine (-> verify with Unigine Valley for OpenGL performance and LuxMark for OpenCL), there's not much you can do.
