How to activate dlss 4.5
Last updated: April 1, 2026
Key Facts
- DLSS is NVIDIA's Deep Learning Super Sampling technology that uses AI to upscale lower-resolution images for better performance
- DLSS requires an NVIDIA GPU (RTX series or newer) and the latest graphics drivers for optimal functionality
- Different DLSS versions offer different quality modes; newer versions include Frame Generation for additional performance gains
- Game support varies—not all games implement DLSS, so you must verify your specific game supports it before attempting activation
- Enabling DLSS typically improves frame rates by 30-80% depending on the selected quality mode and game engine
What is DLSS?
DLSS (Deep Learning Super Sampling) is NVIDIA's proprietary technology that uses artificial intelligence to improve gaming performance without sacrificing visual quality. Instead of rendering at native resolution, the game renders at a lower resolution and DLSS intelligently upscales the image using neural networks. This process dramatically improves frame rates while maintaining image quality comparable to native rendering.
System Requirements
To use DLSS, you need an NVIDIA GeForce RTX graphics card (RTX 20-series or newer). Older NVIDIA cards and non-NVIDIA GPUs (AMD, Intel) cannot use DLSS. Additionally, you must keep your NVIDIA drivers updated to the latest version, as older drivers may not support the latest DLSS versions or newly released games with DLSS support.
Updating Your Graphics Driver
Before attempting to enable DLSS, update your GPU driver. Download the latest driver from NVIDIA's official website or use NVIDIA GeForce Experience for automatic updates. Restart your computer after installation. Outdated drivers are the most common reason DLSS features fail to activate or perform poorly, so this step is critical for success.
Enabling DLSS in Games
Once your driver is current, launch your game and access the graphics or video settings menu. Look for DLSS, NVIDIA DLSS, or AI Upscaling options. Not all games support DLSS, so if you don't see the option, your game may not be compatible. If available, enable DLSS and select a quality preset: Performance mode maximizes frame rate with lower visual quality, Balanced mode provides equilibrium, and Quality mode offers minimal performance improvement with best visuals.
Troubleshooting Common Issues
If DLSS won't activate, first verify your GPU supports it and your driver is fully updated. Check game-specific requirements—some games require specific driver versions for optimal DLSS support. Restart both your game and computer. If the option still doesn't appear, the game may not support DLSS or it may require additional setup outside standard game settings. Consult the game's official support page for compatibility information and recommended settings.
Related Questions
What's the difference between DLSS and FSR?
DLSS is NVIDIA's proprietary AI upscaling exclusive to RTX cards. FSR (AMD FidelityFX Super Resolution) is AMD's open-source alternative available on broader hardware with slightly different quality characteristics.
How much performance improvement does DLSS provide?
DLSS typically improves frame rates by 30-80% depending on quality mode and resolution. Performance mode offers the largest boost, while Quality mode provides minimal gains with best visual results.
Does DLSS reduce visual quality?
Modern DLSS versions maintain visual quality very close to native resolution while boosting performance. Quality mode shows minimal difference from native rendering, while Performance mode involves more noticeable visual trade-offs.
