DLSS (Deep Learning Super Sampling) is NVIDIA's AI-powered upscaling technology built into the Nintendo Switch 2. It's one of the console's most significant technological advances.
What DLSS Does
DLSS allows games to render at lower resolutions internally while outputting crisp, high-resolution images. A game might render at 720p internally but display a clean 4K image that looks nearly as good as native 4K—while running much smoother.
How It Works
The Switch 2's NVIDIA chip uses machine learning to intelligently upscale images:
- Game renders at a lower internal resolution
- AI analyzes the image and predicts detail
- Output is a higher-resolution, cleaner image
- Performance stays smooth because the GPU does less native rendering
Two DLSS Versions on Switch 2
| Version | Use Case | Quality | |---------|----------|---------| | Standard DLSS | Upscaling to 1080p | Excellent image quality with great motion clarity | | DLSS Light | Upscaling to 1440p/4K | Great stills, some motion artifacts due to disabled reconstruction |
Real-World Examples
| Game | Output Resolution | Technology | |------|------------------|------------| | Hogwarts Legacy | 1440p | DLSS Light | | Fast Fusion | 4K/60fps | DLSS Light | | The Tourist | 4K/60fps | DLSS Light |
Benefits
- 4K output that hardware couldn't achieve natively
- Better frame rates at higher visual quality
- Enables ray tracing that would otherwise be too demanding
- Backward compatible games can be upscaled to 4K when docked
DLSS makes previously impossible visual experiences achievable on Nintendo hardware.
