Question

Didn't get expected rendering speed boost from NVidia 970GTX to 1080Ti

I"ve got a ton of rendering to do for an upcoming conference and I thought I'd double my rendering speed witching to the new graphics processor (using CUDA setting).

The rendering is basically two 1080p video streams that get reduced top picture in picture with the output again being 1080p. I know different video processors make a difference because I've carried around a 10 minute benchmark I use over and over for testing between different devices (previous results pasted below).

The 970GTX and 1080Ti are giving me almost identical rendering results.  Is that to be expected on what I'm doing? (my computer itself has 64Gig Ram, i7-5820K processor).

    If you want to run my hardware stress test using Premiere Pro, download my PPBM and run it with both your GTX 970 and the GTX 1080 Ti.  You  should see a major difference between those two.  I am suspecting that you are not using many GPU accelerated effects and features with you benchmark.  Using my benchmark you should see ~100% GPU usage when you run the MPEG2-DVD GPU Accelerated timeline.

    which project/timeline is a good one to run. Maybe i can run, send you result and you can tell me if all is normal.  I don't have the 970 installed any more.

    In case Bill doesn't get back to you right away: Run his whole test. The results can be helpful. The only reason not to see a difference in your results is that there is something else that is not up to the task. This also allows comparisons to other systems.
