Which of my two installed GPU’s will Resolve Lite use (Windows)
Installed on my Windows box, I’ve got a GTX460 feeding my displays and a GTX570 that I want Resolve to use for a GPU.
How do I know Resolve is using the GTX570?

Playback speed changes if you use only gui gpu and or secondary.
With dedicated secondary card you get noticable speed pump.
Also in the app start the number of gpus is also shown.

Margus,
Where in Resolve does it show the number of GPU’s utilized?

[Margus Voll] “With dedicated secondary card you get noticable speed pump.

Since this question is specifically titled “Resolve Lite”, this response is moot. Lite only uses one GPU, and is specifically written to run with systems that only have one GPU. I’m going to assume that your second GPU is totally ignored and all processing is being done concurrently on the User Interface and that all others are idling in the bg making your utilities bill larger for no reason.

The BMD Windows docs suggest separate cards for the display GPU and Resolve GPU even for their “1 GPU Installation” so I believe that Resolve must be smart enough to make some kind of decision as to which GPU it uses.

So then it is not using the UI GPU for color remapping and remains a “single GPU” processor.

Solved – I think.
In the “About Resolve” app display Resolve shows the number of GPU’s it’s using, and at app start, Resolve will popup a warning if it’s using the same GPU as the displays.
My About display says I have one GPU, and startup shows no error, so I guess we can assume that Resolve is using the GTX570.
Now I just need to figure out why I’m only getting ~23fps with h.264 clips with minimal grading…
