CUDA is selected but GPU is always working at %0

[burcinesin]

Hello!

I'm having problem with CUDA feature. I have Nvidia Geforce GTX Titan Black. While rendering or working on Premiere and Media Encoder, GPU is always at %0 (I'm monitoring it on Windows 10 Task Manager).
Only CPU is working for all processes. (CUDA is selected as renderer.) Any idea?

Thank You!

Are you using any CUDA accelerated effects?

Yes, I'm using lot of them in one sequence.

Don't trust GPU monitors.  If CUDA is selected in the settings, it's working where it can.

Render in Premier means making preview files.

In Media Encoder too?

Download GPU-Z and look at the Sensors tab.  Here is 99% GPU usage running my Premiere Pro BenchMark (PPBM) when exporting the MPEG2-DVD timeline with GPU acceleration.

Hi burcinesin,

Encoding is a CPU centric process in Premiere Pro and Adobe Media Encoder.

The GPU does accelerate certain items in the overall export process, but not the encoding itself. The GPU will only accelerate the following in the export process: scaling, frame conversion, blending modes, deinterlacing, and color space conversion.

The GPU will also accelerate the processing of GPU based video effects, including the Lumetri color effect.

Thanks,

Kulpreet Singh

No, a día de hoy premiere y media encoder pueden utilizar las capacidades de codificación de hardware si utilizas una tarjeta gráfica compatible y un códec que ésta soporte (h264, hevc), y que la configuración de tu OS, drivers, etc., lo permitan.

The CPU is still the central processing unit, GPUs are only an assitant to the CPU. And use completely different math and code.

So yes, some GPUs now have certain added capabilities for some specialty items like HEVC, but ... again ... the main program (PrPro in this case) has to have code telling the CPU when and for what specific tasks to use the GPU. And of course, recognizing whether any particular GPU has what parts to it.

So  the post you are responding to is FOUR YEARS OLD. Premiere has added a lot of GPU accelerated things in those four years. So that list is old and no longer applicable anyway.

En ninguno de los dos post en los que he escrito y tú me has contestado, he
negado que la CPU sea el centro neurálgico del ordenador. Me refería a que
a día de hoy, en 2022 -soy consciente de los 4 o 5 años de diferencia entre
los posts y mi respuesta-, premiere ya es capaz de utilizar la GPU para
codificar y decodificar archivos con ciertos codecs que soportan éstas por
hardware.
Entiendo que ha pasado el tiempo, simplemente respondo a estos temas
porque, de la misma manera, yo he abierto un topic y me gustaría que me
respondiesen. En este caso, estoy aportando la información de la que
dispongo: me encuentro haciendo tests de codificación y decodificación con
diferentes GPUs y las pruebas me han aportado esa información.
Solo espero que este foro le sea de utilidad a otras personas con
inquietudes parecidas a las mias.

Un saludo
