Can I choose which GPU to use?

You can select which application should use which GPU in Nvidia control panel. The Slicer main application is SlicerApp-real.exe, you need to select that executable (Slicer.exe is only the application launcher).

Thanks, Andras.

I’m using approx. 300x400x330 images, Volume Rendering and large meshes.

As a reference, here’s what I did:

1. Go to Desktop
2. Right click and select NVIDIA Control Panel
3. On the left panel, 3D Settings → Manage 3D settings
4. Open Program Settings tab
5. Click on Add and Browse for the app (in my case, C:\Program Files\Slicer 4.9.0-2018-06-02\bin\SlicerApp-real.exe
6. Select the preferred graphics processor: “High-performance NVIDIA processor”
