davinci resolve second gpu test
Posted by John Petaja on February 24, 2012 at 7:28 amAvid editor just dipping my toe into resolve here.
Starting into a project that I would like to test resolve lite on. Red media (scarlett 4k)
I’m on a mac pro 3,1, and Just installed the nvidia gt 120 and gtx 285.Here’s a silly question. How can I tell if the gtx is being utilized by any software? My mac recognizes it, but I’d love to know it’s actually being used.
Are there any apps that can test the second gpu to see if I’ve installed it correctly?
fun side note: can avid take advantage of a second gpu?
Thanks!
early 2008 Mac pro running lion 10.7.2.

Nope, Avid can not
Resolve will tell you if its not working.A slice of color…

February 24, 2012 at 3:30 pmHey John,
Just to let you know, Resolve Lite on a Mac is limited to 1 GPU, where the full Resolve for Mac is limited to 3 GPUs. Blackmagic’s comparison page for Resolve is actually super comprehensive!

Now, whether or not Lite can use 1 GPU for the GUI and the other GPU for grading…that I’m not sure of. My heart leans towards, “Maybe.”

February 24, 2012 at 3:52 pmJust fired up resolve. in the about resolve window it does say 1 gpu. This makes me quite sad. For some reason I thought I read that lite could still use the second gpu, as resolve wants to not use the display card for processing.
downloaded cuda-z. the gtx 285 is there and processing. And boy the 120 sure is a slow little card by comparison.
Might have to pony up and get resolve. I really wanted to try before I buy.

February 24, 2012 at 4:56 pmEven Resolve Lite will use both GPU’s, but it only uses one non-GUI card’s CUDA cores for node math.
The GUI card is used for preview monitoring. A slow GUI card can contribute to slow preview FPS.

February 24, 2012 at 5:13 pmif resolve says “1 GPU”, that means it uses one card, that’s what you want with a two-card setup.
the 120GT doesn’t count, because it is for the GUI only, that doesn’t count.I saved you 950$ 🙂

February 24, 2012 at 5:17 pmIf there is one (supported) graphics card in the Mac, Resolve is forced to use that for both GPU processing and GUI display driving. And you will get a warning message telling you this is not advised due to the performance hit. And it will display 1 GPU being used in “About DaVinci Resolve”. But it will work.
If there is more than one (supported) graphics card in the Mac, the card connected to the GUI display is NOT used for GPU processing. It’s only driving the GUI display. Leaving the other card(s) available for dedicated GPU only processing.
In Resolve Lite, if you have 2 cards, one is used for the GUI, and the other is used for GPU processing. If you have more than 2 cards, Resolve Lite will still only use 1 card for GPU processing. So you will always see 1 GPU in the “About DaVinci Resolve” dispaly in Lite, no matter how many cards you use. But having the second card for the GUI display leaves the 1 GPU card fully available for GPU only processing, so performance is better. So 2 cards is still recommended for Lite for best performance.
In full Resolve, the number of GPU’s shown in “About DaVinci Resolve” should match the total number of graphics cards in system, minus the one connected to the GUI display.

Very excited to fire up resolve this weekend. Now if only I could afford a turbobox pci-e chassis so I could keep my ati card in my box. -

My impression was that Lite was limited to an upper resolution of 1920×1080. But you might be scaling the “4K’ down to HD, so maybe that’s allowable.

When I first saw Lite being tested, the colorist had imported Arri Raw files into the media pool and was coloring (what at least was my impression) those very same files. Looking at the Blackmagic comparison table now, it seems that Lite can indeed handle 2 and 4k material in the timeline, but can only render out to a maximum of 1920×1080.
So essentially, you can color with that comparatively large latitude at hand, but you’ll only be able to get HD quality material as an end-product.
At least, that’s the impression that I get, looking at the stats.

February 27, 2012 at 5:27 amThe Resolve Lite resolution limitation is in setting the timeline and render resolutions, not the source resolution.
