Clear VFB in between renders – When enabled, the frame buffer is reset to black before each rendering. When disabled, the last render stays on and is gradually replaced by the new one.
Render stamp – When enabled, text with render information overlays on the bottom right corner of the rendered output. You can click the little > button before the checkbox to see the list of all available %-variables you can use.

Type – The image pre-filters suppress Moiré patterns and other artifacts by slightly blurring the image. Most filters produce visually almost equal results.
Available filter types are:
High Quality – This filter produces better anti-aliasing and DoF than other filters. It does not work with AI denoising. Box – This filter has the most significant blurring of all the filters. Tent – This filter offers a good tradeoff between blurring and sharpness. Symmetric tent – This filter is a variant of the tent filter with bigger diagonal blurring. Parabolic – This filter has the second most significant blurring of the filters. Hann – This filter has low diagonal blurring and a smaller tail than the other filters. Blackman-Harris – This filter is the sharpest, resulting in the least blurring of all the filters (except for None). None – This option disables the filtering entirely, resulting in a perfectly sharp image.
Width [px] – The filter radius in pixels. A larger value slightly blurs the image to improve anti-aliasing and removes the Moiré effect. The default value of 2.0 works fine in most cases.
Highlight clamping – Clamps all samples to this maximum value before they are written into the frame buffer. This can help to reduce noise and improve anti-aliasing around bright light edges at the cost of bias. Setting the value too low results in visibly clamped highlights. Set to 0 to disable for unbiased, highest-quality output.
