The main rollout for the Quicksilver hardware renderer lets you adjust render quality by setting either the time to spend on rendering, or the number of iterations to perform.

- Rendering Duration per Frame
- Lets you specify how to control the process of rendering.
- Time Set the duration of the rendering in Minutes and Seconds. Default = 10 seconds. Note: The number of iterations in a particular time interval depends on CPU/GPU speed and on available memory.
- Iterations (number of passes) (The default.) Set the number of iterations to run. Default=256.
- Time Set the duration of the rendering in Minutes and Seconds. Default = 10 seconds.
