There are two Render Quality settings, each with a different balance of three variables: eye rays, reflection samples, and lighting accuracy.
Setting | Eye rays variable | Reflection samples variable | Lighting accuracy variable | When to use | Speed |
Standard | 4.0 | 1 | Low | More accurate than Draft. Perfect for quick visualization during design. | 4x |
Final | 32 | 16 | High | Lower noise and broader tonal range than High. Perfect for archival rendering, when speed is not a priority. | 20x |

Eye Rays
Ray tracing analyzes the way simulated rays of light bounce around in your 3D scene. Eye rays refers to the number of initial simulated light rays being traced per pixel in the final rendered image of your scene. The more eye rays that are calculated per pixel, the greater the accuracy of this variable's final value.
Reflection Samples
The quality of a calculated reflection depends on the amount of detail in the texture of the surface. Reflection samples refers to the amount of detail per eye ray. A higher number of reflection samples results in reflections that appear more photorealistic.
Lighting Accuracy
Rendering a scene requires analyzing all the light sources present, for each pixel in the final image. This analysis can often be simplified with little perceptible effect, resulting in dramatic speed improvements. Lighting accuracy refers to the amount of simplification applied to the lighting in your scene when each pixel in the final rendered image is calculated. Draft quality mode further simplifies the lighting calculation by averaging groups of pixels with similar properties.
