Viewport Acceleration

RealFlow simulations often contain millions of particles. Displaying these large numbers of elements can be a heavy task for graphic cards, and might slow down your viewport actions. One method to accelerate these operations is to use

View > Fast View (F)

When this mode is enabled all scene elements will be displayed as bounding boxed while rotating or panning the viewport.

With “Visualization Level of Detail” only fluids are affected. When you click on the icon (see below) a small menu appears with different settings to choose from.

During simulation you should always disable RealFlow's viewport, because it takes some (CPU) time to paint and display the changes between two frames. With a disabled viewport you can save around 30% of the total simulation time. This is the shortcut:

Alt + D

Please also use just a single view, e.g. front or side, during simulation – otherwise RealFlow has to update not just one viewport.
