This is especially true for the Progressive sampler, which stores the entire image in memory before beginning the rendering process. Image samplers require a substantial amount of RAM to store render information. Disabling the Progressive toggle when Swarm is Enabled can be helpful for cutting down on network traffic and reducing the loss of information if work is not completed by one or more Swarm nodes.Combining the VRayDenoiser with Progressive renders can help with cleaning up render noise.This can also be useful when rendering test animations, where the entire sequence must be rendered within a certain time frame. Progressive is also helpful when a set amount of time to spend per render is needed.

Additionally, the render can be stopped at any time before resolving completely.

When Progressive is disabled, the image is rendered in buckets.

Disabling the Progressive toggle is the same as using the the Adaptive image sampler type in previous versions of V-Ray.
