Interactive Denoiser Primary (when moving)– Sets the type of the denoiser that will be used in the viewport during navigation or object manipulation. DLSS Ray Reconstruction – Uses NVIDIA DLSS 3.5 with Ray Reconstruction that offers real-time AI denoising for a better ray-traced image quality. NVIDIA OptiX AI – Uses NVIDIA OptiX AI denoiser that offers accumulated samples and denoise when the scene is static, offering a high fidelity image that is visually noiseless. Intel Open Image Denoise – Uses Intel Open Image Denoise that provides quality greatly superior to the Vantage denoiser when many samples are accumulated over time. It may also be slightly better than NVIDIA OptiX AI, but slightly slower as well. Vantage – Uses the native Vantage denoiser that produces sharp initial image, but some artifacts remain even when more render samples are accumulated. Secondary (when static) – Sets the type of the denoiser that will be used in the viewport when nothing in the viewport is moving or being manipulated. Same as Primary – Uses the same denoiser that is set as Primary. NVIDIA OptiX AI – Uses NVIDIA OptiX AI denoiser. Available when DLSS Ray Reconstruction or Vantage denoiser is set as Primary. Intel Open Image Denoise – Uses Intel Open Image Denoise. Available only when Vantage denoiser is set as Primary.
Switch after – nder samples that need to be accumulated before switching to the NVIDIA OptiX AI denoiser or Intel OIDN when the Secondary denoiser type is set to other than Same as Primary. Spatial filter strength – . Only available when Vantage denoiser is set as Primary.
Spatial denoising – Enables/disables spatial denoising for the Vantage denoiser. Only available when Vantage denoiser is set as Primary. Special iterations – Specifies the quality of the Vantage denoiser. Higher values make denoising more stable. Only available when Vantage denoiser is set as Primary.
Temporal denoising – Enables denoising of the previous frames. When disabled, the current frame is denoised on its own. Only available when Vantage denoiser is set as Primary.
Temporal AA – Applies time based anti-aliasing. Only available when Vantage denoiser is set as Primary.
NVIDIA OptiX AI Denoiser Legacy mode (interactive and offline) – In some specific cases may produce better results than the new mode. For example, when there is ghosting on deformable meshes in offline sequences.
Displacement Tessellation level – Specifies the level of tessellation for geometries that have displacement. Available levels are None, Low, Medium, High. None means that no tessellation is applied to the displaced mesh. Note that the High tessellation level requires more GPU memory. Per-triangle tessellation level – When enabled, allows the tessellation rate to vary within the mesh based on distance to the camera, potentially saving memory. If the fixed tessellation at the given camera distance is too low, this option may use slightly more memory than the fixed tessellation rate. Disable this option if the transitions between different tessellation levels in the mesh are too visible. For optimum results, the base mesh should have some tessellation. Emulate 2D displacement – When enabled, 2D displacement is rendered as 3D displacement, using more memory. If this option is disabled, 2D displacement does not render. It is recommended to enable Per-triangle tessellation level when using this option.
Viewport Fill Filter sharpness – Applies filter sharpness only when Viewport fill button is enabled and the viewport is stretched larger than the render resolution. When set to 0,.0, no filter sharpening is applied.
HDR The HDR options are available only when an HDR device is detected. Enable HDR – Enables HDR output on/off. White level – HDR white level in nits. Specifies the brightness of a white color with intensity 1. Max luminance – HDR maximum luminance in nits for clamping the output. NVIDIA Optix AI denoiser requires NVIDIA display driver 466.11 and newer.

DLSS Ray Reconstruction denoiser requires NVIDIA display driver 537.13 and newer.
