Are there any out of the box operations one can do to stress test GPU usage via Paraview.
Currently, I load the head volume render to exercise the OpenGL operations.
I may have a brief access to some new hardware to try out Paraview and was hoping to have something I can do with the latest Paraview out of the box without having to download external dataset.
If the above is not feasible, I will then consider e.g. large \*.vti files to download
Thank you in advanced.

You can create large datasets using the **Wavelet** or **Unstructured Cell Types** sources.

I am trying out Wavelet and viewing the volume representation.
Is there a way to increase the density of the points that comes out of the wavelet node ? I tried clicking on the `gear` in the hope there are some additional parameters I can tweak but so far, I have not found one that increases the point density (which I hope will create denser volume there by putting more load on the GPU when rendering)

The **Whole Extent** property in the _Properties_ tab is what controls the number of samples in each dimenion. Hover over the property for more information in the tooltip.
