Hi Andy,

I’m using 10.8.3. I didn’t update but I have since tried updating to 10.8.5 without any luck.

Thanks

I was getting 19.5 fps on the 4,1 and I was getting about 16.5/17 on the 3,1 so I was expecting that ratio to stay fairly similar, which it does without a GPU.

With the GPU added the 4,1 really takes advantage of the new optimising but the 3,1 just does not seem to, except for playback.

8.2 only ever really used the GPU for playback, as far as I’m aware.

Thanks

Thanks Rohit,

When using Resolve 8 I would get the same speed on my 4,1 and 3,1 (with Quadro4000).

When using Resolve 9 I get 50+ fps on the 4,1 with the Quadro and 25 without.

I get 25 with or without on the 3,1.

THe Quadro is definitely speeding up render times on the 4,1 but seems to have little to no effect on the 3,1.

There surely can’t be that much difference between the 3,1 and 4,1. I would maybe expect something like 35fps with the Quadro.

THey both have 12GB RAM.

Thanks again.

Hello All,

Thanks for all your help and suggestions.

I’m back home now where I’ve been able to try a few tests.

I’ve tried the Quadro in another Mac (4,1) and it is working fine and giving me around 50fps.

I’ve upgraded to 12GB and it does not seem to have made any difference at all.

I’ve tried different operating systems, re-installing drivers, trying a GTX285, swapping cards around, different GUI card.

It does not seem to make any difference, I can’t really get much more than 28fps, and an average of 23.

I can’t believe there would be that much of a difference between a 4,1 and a 3,1.

It feels like it’s not taking advantage of the GPU when rendering, although it seems to be using a bit of it.

Any help would be greatly appreciated.

The only thing I’ve not been able to try is having the same setup in a different 3,1 Mac Pro.

I’ve attached an activity monitor screnshot when rendering – 4541_render.jpg.zip

And When playing back – 4540_playback.jpg.zip

Thanks again
