Max Passes –Limits the maximum number of passes rendered in the interactive rendering mode.

note
For interactive render regions, this value is best left at 0 to ensure that new or changed regions render (otherwise, they do not render if the max passes value has already been reached).
Force Path Tracing – When on, Path tracing is always used as a primary and secondary solver in interactive rendering. This keeps the interactive rendering responsive, avoiding the cost of UHD Cache precomputation.
Enable Motion Blur - This option is on by default, if this option is disabled then you will not be able to see motion blur in 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 on NVIDIA GPUs when 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.
