I'm running a dual boot Windows 10 / Hackintosh (Yosemite) machine. I've had it running for about two years. Originally I had an EVGA GTX 670 in it, but I replaced it with a 970 about a month ago.
I just imported a project into Davinci Resolve and I'm getting terrible performance. With a relatively simple 2K ProRes project, I'm getting about 10fps when I try to play through the timeline.
I've had plenty of unanswered questions with Resolve with respect to display and rendering GPUs, so I closed that and ran NovaBench.
Here's the results from my Hackintosh. Most telling is: Graphics Tests (Score: 177) - 3D Frames Per Second: 565
I booted into Windows 7 and ran Novabench from there. Here's those results. Graphics Tests (Score: 1163) - 3D Frames Per Second: 2979
I'm hoping that something is wrong and I'm not doomed to poor performance with a 970 GTX because I picked a not-very-compatible card or something. I'm using the most recent NVIDIA web drivers.
In fact, I found the Novabench I ran with the 670 GTX. It performed better. Graphics Tests (Score: 203) - 3D Frames Per Second: 685
Possible causes:
I'm really at a loss. I wonder if it's that the web drivers aren't good enough compared to the drivers I'm able to install in Windows? Also, my i7 chip has an integrated GPU on it. Everything that I read on my computer displays the GTX 970 (About This Mac, Davinci Resolve, Novabench), but is there any possibility it could be interfering? I turned off "internal graphics" in the Gigabyte bios, but it didn't appear to change.
Here's my general build:
Yosemite 10.10.3
Gigabyte GA-Z77X-UP5 TH ATX LGA1155
Intel Core i7-3770K Quad-Core Processor 3.5 GHz 8 MB Cache LGA 1155
EVGA GeForce GTX 970 FTW ACX 2.0 4GB GDDR5 256bit
16GB RAM (8GBx2), 240-pin DIMM, DDR3 PC3-10600
