Attached the power usage issue i am facing. Pix4D magic has been using 99% of CPU and the graphics card is not sharing the load properly. The power usage is so high that the UPS is stopping the process in the middle. I have contacted Nvidia, they said its Pix4D software issue. I need some help with power optimisation for the CPU before my PC gives up. I am using AMD Ryzen 5950X processor, RTX 3070Ti.

Hi @rayavarapunani,

You have also opened a ticket with the Technical Support.
I have answered to you on a private message.

Best,

You must have a very small UPS. Max power draw for the 5950x is less than 150w. Your 3070ti will draw nearly 300w. You need a bigger UPS.

Thanks @Andrew_Milanes .When i run a project, the UPS triggers and stops the whole process. I have disconnected the Monitor from UPS and it. This time it was ok. Need to get an inverter.

Hi Nikoleta,
I am running into the same problem. My CPU is at100% at times and GPU stays at 12% or so.
My processor: Intel(R) Core™ i9-10900X CPU @ 3.70GHz 3.70 GHz
GPU: NVIDIA GeForce RTX 3080Ti
My ups output is 500w
I do have my PC connected to the surge protected side and not the battery supported surge side. Could that be my problem?
I put high performance on my graphic settings for Pix4D Matic, but it is still not sharing the load of the cpu

Hi Im currently testing Pix4d mayic ahead of some future projects I’ll have in the incoming months, and I gave been running into the same problem. Almost all the time ny cpu usage is set on 100% and the gpu at 20% or lower
I have a x99 family cpu and a rtx 3070 gpu.

Hi gomesgrafia,

Welcome to the community!

If the problem you are referring to is a noticed imbalance between the CPU and GPU usage percentages, this would be expected behavior. Processing is intended to be done both on GPU and CPU. As long as the GPU is recognized and supported, then it will be utilized to the fullest extent possible. Not all tasks can be processed on GPU and likewise with the CPU.

Using the Hardware Accelerated Algorithm when available, can utilize the GPU further:

This option allows switching between the densification algorithms:

  • Hardware accelerated (Default): The densification will be computed using a GPU-capable algorithm. This option can contribute to reduced processing time.
  • Standard: The densification will be computed using the standard algorithm.

  • Algorithm: Allows switching between the orthomosaic creation algorithms.
    • Standard (Default): The generation of the orthomosaic will be computed using the standard algorithm.
    • HW accelerated : The generation of the orthomosaic will be computed using a GPU-capable algorithm. This option can contribute to reduced processing time.

You can also set PIX4Dmatic to use a discreet graphics card (Windows 10 and Windows 11).
