GTX 680 Incredible render gains with El Capitan

I am setting up another boot drive with El Capitan (the old one is Yosemite)
Both are on SSD internals.

I am getting WAY faster render times and so far I am not finding anything I need to render at all.
For example:
1080 clip with 3D atmosphire title above it (backdrop on the title is off)
The Clip has, bokeh, newsprint, color correction, mask, and transformed (zoomed a bit)
Below the video clip is the clouds generator to reveal the mask.
The 3D title has, camcorder and decal filters.
Playback without render and no drop frames.
If I want to render it, 9 seconds to render the area (7 seconds long)

On yousemite, I cant get no where near this render time, and forget playing it back without dropped frames unrendered.

I am still setting up the OS (and making various backups), so no testing yet with any 3rd party filters or any filters I made in motion (none have been installed yet).
If you have Premiere or AE, the difference's is comparable to with / without CUDA. Excellent performance gains!

Here is the system:

Chipset Model: NVIDIA GeForce GTX 680
Type: GPU
Bus: PCIe
Slot: Slot-1
PCIe Lane Width: x16
VRAM (Total): 2048 MB

Model Name: Mac Pro
Model Identifier: MacPro5,1
Processor Name: 6-Core Intel Xeon
Processor Speed: 3.33 GHz
Number of Processors: 1
Total Number of Cores: 6
L2 Cache (per Core): 256 KB
L3 Cache: 12 MB
Memory: 32 GB

Hey Kurt,

Great to hear you are seeing that kind of performance boost with titles and effects.

I just finished a BruceX test on El capitan,

I now averaged about 60 seconds for the test, Used to do about 70, pretty much right where Alex4d expected before Metal.

I have attached my system specs. I wrote the file to the startup disk which is a 1TB fusion Drive.

I was curious...and I am happy!

Just installed 2x 7950's using Y splitters (yikes) powering 2x 27"LED cinema displays on the bottom card.

Model Name: Mac Pro (Early 2008)
Model Identifier: MacPro3,1
Processor Name: Quad-Core Intel Xeon

BruceX test - ProRes422 - average over 3 runs
1x 7950 - 50 secs
2x 7950 - 32 secs

BruceX test results ProRes 422:

2013 iMac 27, 3.5Ghz i7, 32GB, GTX-780m, 10.11.1, FCPX 10.2.2, 3-run average: 45.3 sec

2015 top-spec MacBook Pro 2.8Ghz i7, M370X, 10.10.5, FCPX 10.2.2, 3-run average: 46.8 sec

2015 iMac 27, 4Ghz i7, 32GB, M395X, 10.11.1, FCPX 10.2.2, 3-run average: 17.1 sec

I don't know why the 2015 iMac 27 is so fast on BruceX. In other general testing (LR import/export, FCPX import/export, Neat Video NR, etc) it is about 15% faster, the expected difference between 3.5Ghz and 4Ghz CPU. It's about 24% faster on Cinebench.
