Turbulence FD don't want to render with my GPU
on Jul 16, 2017 at 8:23:22 pm

Hello.

So I'm trying to do a simulation with the Turbulence FD plugin. The default render hardware is my cpu and it takes so much time to render a frame.
When I choose my gpu instead of my cpu it switches back to my cpu. I don't get it. I can select my gpu while rendering and shows the vram from the gpu, but after few seconds its switching again to my cpu. I updated my drivers to the latest and the internet isn't helpful. Maybe some of you guys have a solution.

My gpu: GTX 1060 6GB Gainward Phoenix
CPU: i5-4690k 4,4GHz

Hi Maxim,

I know that Turbulence FD will switch back to the CPU when it runs out of GPU memory, but I wouldn't think that would happen after only a few seconds unless you are trying to run a massive simulation.

If you want to post your project file I'll try running it on my GTX 980 Ti 6GB and see what happens.

When you say "render" I'm assuming you were referring to running the cached simulation. When I ran it, it took about 3 min. 30 seconds for the full 300 frames. As far as I could tell it was running on the GPU the whole time, indicating that it was using around 1.7GB of the available 6GB. If I run it with CPU selected it estimates over 20 minutes.

What do you see when it switches back to the CPU? Does the selection window switch to that, or what?

I am leaving to go to my granddaughter's 1st birthday party, so I will check back later.

Do you have the most recent nVidia drivers installed? If not that could be the problem.
