Render Quality
Render Quality is a setting in nXtRender which allows you to create high-quality renderings, or draft-quality renderings.
Draft quality renderings process about 4 times faster with some loss of rendering quality. The user can then re-render at high-quality without re-extracting or reloading the scene.
High Quality Rendering - 40 passes - 78 seconds rendering time.
Draft Quality Rendering - 40 passes - 20 seconds rendering time.
The setting is on the Render Setup Tab of the Options Dialog
