First of all I would like to apologize if this has been asked before, as I couldn’t find an answer via the search, and also I wasn’t sure which section to put it in.
My question is: When rendering video with NVENC enabled on my Quadro K620, if I go into nvidia-settings (Nvidia’s control panel for Linux), it shows a percentage next to GPU Utilization and Video Engine Utilization. What puzzles me is that the percentage is always really low. GPU Utilization barely goes past about 4%, and Video Engine Utilization barely goes past about 10%.
Why is my Quadro not utilizing its’ full power? Is this down to a bottleneck with my CPU, drivers, video editing software (I’ve tried both Kdenlive and Shotcut and the percentage is still low), or something else? Does anyone else have experience with this?
When rendering (using all 4 cores of my i5 2500s, and enabling the parallel processing option in the video editing software), my CPU always works at near full power, but the GPU doesn’t. I have 8gb of ram, which is never maxed out when rendering, and neither is the ram on the GPU, so it can’t be that.
I’d love to know how to increase the percentage of the GPU utilization, as this would then surely get the full rendering speed from the Quadro.
I’m using driver version 455.38
Thanks in advance.
