Real time playback issue with GTX 285 & GT 120
I have installed a NVIDIA GeForce GTX 285 and a NVIDIA GeForce GT 120 in my Mac Pro to be able to run DaVinci.
However, my playback is far from real time. With no correction layer added my playback time is roughly 16 fps for a 1080p clip and as soon as I start to add even simple corrections I’m down to 8 fps and less. What can be wrong?

Exactly what kind of Mac Pro is it?
What kind of files are you playing?
Prores?
Image sequence? -
Make sure you don’t have your monitor plugged into the GTX card also.

“How many GPUs is Resolve reporting?

You mean “Old Ben”? Ben Kenobi?

In this configuration it will report only one.

It will probably only report one even if it is using the second GPU as a render device, as that is how Resolve counts things. The main thing is to free up the second GPU, and a common error is connecting it to a monitor. Does it ever warn that it is also using the GUI card as a media processor?

A 2.66 GHZ Quad-Core Intel Xeon with 8 GB 1066 MHz DDR3 ram. I’m grading ProRes 422 files.

The monitor is plugged into the GT 120.
-
1 GPU is reported at the About DaVinci Resolve page.

What MODEL # MacPro do you have? A 3,1? Do you only have a single CPU? As Joseph asked, when you launch Resolve, do you get any warnings or messages, and if so, what exactly?

A 2.66 GHZ Quad-Core Intel Xeon with 8 GB 1066 MHz DDR3 ram. I have no warnings when starting up DaVinci.
