Maximum box sizes for various amounts of GPU memory

The most important factors influencing memory usage for the 3D refinement jobs are the box size of the volume and particles used, as well as the computational batch size. Below is a tabulation of the approximate maximum volume box sizes that are supported by various GPU RAM sizes, valid for the following job types:
    Homogeneous Refinement
    Non-Uniform Refinement (NEW!)
    Helical Refinement (BETA)
    Local Refinement (NEW! BETA)
GPU VRAM (GB)
Approximate Max Volume Box Size (px)

In most 3D refinement and reconstruction jobs, the computational batch size can be changed by setting the "GPU batch size of images" or "Computational minibatch size" parameter. Decreasing this may alleviate GPU out-of-memory issues.
