Max passes – Limits the maximum number of passes rendered in the interactive rendering mode. Note that for interactive render regions, this value is best left set to 0 to ensure that new or changed regions will render (otherwise, they will not render if the max passes have already been reached).
Force path tracing – When on, Path Tracing is always used as a primary and secondary solver in interactive rendering, even when UHD Cache is selected for regular rendering. This keeps the interactive rendering responsive, avoiding the cost of UHD Cache precomputation.
Enable motion blur – When enabled, this option allows the motion blur to be computed in the interactive rendering.
Fast preview denoise during render – When set to an option other than None, the image is iteratively denoised during the render. This replaces a noisy render preview with a noiseless, albeit low-quality image that gets progressively refined as the render converges. It can help to get a quick estimate of the overall lighting in the scene. There are two denoising modes available:
Fancy Bullets
Optix– Also known as "NVIDIA GPU AI" is a very fast denoiser that is available only onNVIDIA GPUswhen the optional "NVIDIA AI Denoiser" Corona component has been installed.
Intel– Also known as "Intel GPU AI" or "Intel Open Image Denoise" is a slower denoiser but provides a higher quality result.

The In Corona 11, the Intel GPU AI denoiser is currently available for supported only by Windows-based systems and its GPU mode only works on NVIDIA GPUs.
