NVIDIA has revealed that DLSS 5 will give developers fine-grained control over AI-enhanced rendering through multiple AI models, per-object customization, and adjustable visual intensity, aiming to preserve artistic intent while improving image quality on a single GPU.
Summary
- NVIDIA provided the first detailed look at DLSS 5 during SIGGRAPH, explaining how developers will be able to control the technology.
- DLSS 5 is designed to address criticism that AI-generated rendering could alter a game's intended artistic style by giving developers extensive customization options.
- The technology introduces a generative rendering stage after the game engine has produced a conventionally rendered frame.
- The original game renderer continues to determine:
- Geometry.
- Camera positioning.
- Lighting setup.
- Scene composition.
- DLSS 5 then enhances the rendered frame by improving:
- Materials.
- Shadows.
- Reflections.
- Surface detail.
- Other visual effects.
- NVIDIA says DLSS 5 is intended to complement, not replace:
- Rasterized rendering.
- Ray tracing.
- Path tracing.
- The company describes generative rendering as a third neural rendering category, alongside reconstruction and function approximation.
Three major technical challenges
- NVIDIA outlined three primary engineering challenges addressed by DLSS 5:
- Preserving developers' artistic intent.
- Maintaining temporal stability.
- Delivering acceptable performance.
Preserving artistic intent
- AI image generation can unintentionally change important visual details such as:
- Facial features.
- Scars.
- Clothing details.
- Character identity.
- To prevent this, DLSS 5 relies on:
- The original rendered frame.
- Albedo buffers.
- Surface normals.
- Lighting data.
- Other engine-generated information.
- These inputs help keep AI-generated enhancements faithful to the original artwork.
Temporal stability
- Unlike traditional video-generation AI models that process multiple future frames, games require immediate responses to player input.
- DLSS 5 operates causally, processing one frame at a time without future-frame information.
- Motion vectors and additional engine data are used to reduce:
- Shimmering.
- Image drifting.
- Swimming artifacts.
- Frame-to-frame instability.
Performance
- NVIDIA says it compressed knowledge from larger generative AI models into a compact one-step pixel-space diffusion transformer.
- The model is optimized specifically for enhancing rendered game frames rather than generating entirely new images.
- NVIDIA also indicated DLSS 5 is designed to operate on a single GPU with efficient VRAM usage.
- The company has not yet confirmed:
- Hardware compatibility across the entire RTX 50-series lineup.
- Whether every DLSS 5 model will run on all supported GPUs.
Three selectable AI models
- DLSS 5 includes three separate AI models, demonstrated as:
- Model A.
- Model B.
- Model C.
- Each model produces a different visual interpretation of the same rendered scene.
- Developers are not restricted to a single model throughout a game.
- Different models can be assigned to:
- Individual scenes.
- Environments.
- Cutscenes.
- Other specific portions of a game.
- Models can be mixed throughout gameplay to achieve different artistic goals.
Adjustable intensity controls
- Developers receive two independent adjustment sliders:
- Structure Intensity
- Tone Intensity
- Structure Intensity primarily affects high-frequency visual detail, including:
- Ambient occlusion.
- Reflections.
- Subsurface scattering.
- Fine material detail.
- Tone Intensity controls broader visual characteristics, including:
- Lighting.
- Color grading.
- Overall scene appearance.
Per-object customization
- One of DLSS 5's most significant additions is per-object control.
- The system supports automatic AI-generated masks that can identify characters independently from the rest of the environment.
- Developers can:
- Apply DLSS 5 only to selected characters.
- Exclude characters entirely.
- Use different enhancement strengths for different elements.
- Additional masks can also be created manually within the game engine.
- NVIDIA demonstrated separate controls for objects such as:
- Bottles.
- Grapes.
- Pitchers.
- Other environmental props.
- Every masked object can have its own:
- Structure Intensity.
- Tone Intensity.
- This enables developers to selectively strengthen, weaken, or completely disable DLSS 5 processing on individual objects.
Release plans
- NVIDIA says DLSS 5 will continue evolving based on feedback from:
- Developers.
- Artists.
- The technology is scheduled to launch this fall.
- The presentation focused on providing developers with creative control to ensure AI enhancements improve image quality without overriding the original artistic vision.
