Playback not Possible at Full Resolution: Where is the Bottleneck?

Hello,

 

My system struggles to play 4K R3D files at full resolution (1/2 is fine). When looking at the process monitor, the CPU and RAM are not being taxed very much so I'm guessing it can't be those.

 

The HDD I've put the footage on is an SSD which appears to have a read speed of 540mbs.

 

The specs of my system are:
CPU: i7 5930K @3.50 GHz
RAM: 32GB
GPU: Nvidia GeForce GTX 760

 

Many thanks

To elaborate further on Ann's statement:

 

  • Your CPU is outdated these days. Performance-wise, despite having 6 cores and 12 threads, it could barely keep pace with a recent 4-core/8-thread CPU in overall processing power - while consuming much more power than that quad-core CPU.
  • Nvidia had announced the EOSL of all Kepler-generation GPUs in July of last year (or put it this way, these GPUs were placed into legacy support status). And since June of 2020, CUDA support has been dropped completely on all first-gen Kepler GPUs. This meant that display drivers up to and including the 472.98 version will install on that GTX 760 (which is based on the first-gen Kepler GK104 GPU that was used in the original GTX 670), but all CUDA support is now permanently disabled for all first-gen Kepler GPUs in newer drivers since CUDA support will support only the second-gen Kepler GPUs based on the GK110 and GK208 chips. And any "newer" driver releases for Kepler GPUs (which will continue until September of 2024) will fix only critical security issues.
  • Finally, Adobe has no say whatsoever about this. In fact, it is stuck between continuing to support legacy GPUs but leave support for newer GPUs permanently broken, or support the newer GPUs adequately but completely cut off support for everything older. Adobe wisely opted for the latter course (as recommended by the hardware manufacturers).

 

In short, you definitely need an entire new PC in order to run newer versions of Premiere Pro properly.

    It looks like your machine is way under powered to run such files.

    Best is to transcode to edit friendly codec or use proxies.

    Thanks for your response.

     

    I would prefer to work with the original files, and the system is not too far off playing them at Full.

     

    I am trying to work out where it is underpowered. As mentioned, the CPU and RAM appear to be quite adequate so I'm not sure where it is lacking.

    Thanks.

     

    Please can you let me know what MPE hardware is? I can't find anything about it in the link. Also I'm not quite sure what you mean by "present GPU is not supported" -- do you mean the GPU I'm using is not supported by the CPU?

     

    So, even if the process monitor says the CPU is only at 40-50% usage while the footage struggles to play, it probably in fact is the CPU?


    GPU not supported as in CUDA.

    Project Settings > General >

    Yours is most likely set to software.
