Dyverso not using GPU !?

Post by MrCedric11111 » Tue Nov 26, 2019 1:54 pm

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% :shock:

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 :mrgreen:
