GTX 980 ti in Mac Pro Not using CUDA for Premiere Pro 2017CC

[antonios10477683]

Need help, i have 2012 Mac Pro with GTX 980 ti Flashed, I'm able to select the CUDA but its not using the power of the gtx 980 ti to render my selection or play back 4k footage with out dropping frames, i can switch to OpenCL and it runs a little better is there anything i can do to get my CUDA going?  Im running OS X sierra 10.12.4 with all the updated nividia drivers, i also have ran geekbench 4 CUDA test and it seems like its working but not working in premiere pro 2017cc.................Thanks

Run Adobe's GPUSniffer, in a PC it is run in a DOS CMD window I do not do Mac so you will have to translate that to Mac.  Post the results here

Adobe sees the GPU properly so my guess is you are not using any MPE accelerated effects or features.  Lots of people expect the GPU to be heavily used but we find out that they are not using anything that is GPU accelerated. 

You have a five year old system what CPU's do you have?  How much memory?

I suspect that dropping frames that you do not have enough CPU power to handle complex 4K media.

I have a 12 core 3.46 64gb memory 4 sm951 on amfeltec card 4500 read, 4500 write, geekbench at 31000

Fantastic storage system, did you upgrade your CPU's at some time because Apple and/or Intel do not show Xeon E5645 at 3.46 GHz in that 2012 Mac Pro
