Dyverso not using GPU !?

[MrCedric11111]

Hello

I thought that Dyverso used GPU rather CPU, even more when you have seleced it?
I miss something because in my Dyverso scene the CPU works at 100% while GPU 1%

This is a question for hardware experts, and I am not one of those
Nevertheless, it may depend very much on the type of simulation running, if the system has to switch all the time between CPU and GPU, for example. In this case, simulation with a larger amount of particles would benefit more. Also, tools measuring OpenGL or DirectX benchmark values would not be appropriate, because only CUDA-calculations count here. In my case with the melting simulation and around 700k particles, the "GPU load" shown in the GPU-Z tool oscillated always between 0 and 30%. Memory consumption is relatively low with only 1.6GB.

The GPU load with a GPU-render engine, Redshift3D, was up to 70% during active rendering with the same machine. In that situation with 9GB memory load, a different situation.

Thank you for your help Christian!

So If I break my piggy bank for a new pc with a TITAN gpu, in fact it cost me a lot for maybe a little % use of it... I think I’ll wait a bit before a new pc

In your screenshot of the task manager it is showing the 3D load (as far as I understand) if you change the drop-down to show Compute_0 it will show the actual load. I had a similar issue when I thought my cards weren't working in octane
