The world of gaming graphics has been revolutionized by NVIDIA RTX and DLSS (Deep Learning Super Sampling). These technologies, while often mentioned together, serve distinct yet complementary purposes in enhancing your gaming experience. RTX brings realistic, ray-traced lighting, while DLSS uses AI to boost performance and image quality. Understanding how to use them can dramatically improve your gameplay. Here’s a comprehensive guide to help you navigate these powerful features.

How Do I Use RTX and DLSS?

Enabling RTX and DLSS involves a few straightforward steps, primarily within your game’s settings. The exact method can vary slightly between titles, but the general process remains consistent:

Verify Your Hardware: First, ensure that your graphics card is compatible. You’ll need an NVIDIA RTX series GPU (e.g., RTX 2060, RTX 3070, RTX 4080) for ray tracing and DLSS. You can check your GPU in the Task Manager (Performance tab) or Device Manager (Display Adapters). Some older cards like the GTX 1660 Ti may support ray tracing in some games via software, but with limitations. DLSS Frame Generation is exclusive to the RTX 40 Series.
Update Your Drivers: Outdated drivers can hinder performance or prevent RTX and DLSS from functioning correctly. Always keep your NVIDIA Game Ready Drivers updated. You can typically download these from the NVIDIA website or the GeForce Experience application.
Launch Your Game: Start the game that you wish to use RTX and DLSS.
Navigate to Graphics Settings: In the game menu, find the graphics or video settings.
Enable DirectX 12: Some games require you to change the DirectX Version to DirectX 12 before you can enable RTX. If you have this option, change it and restart the game, returning to graphics settings after the restart.
Enable Ray Tracing: Look for an option to enable ray tracing. This might be a simple toggle switch or a more detailed menu with different ray tracing detail levels.
Enable DLSS: Find the DLSS option, usually within the same graphics menu. Select your preferred setting, often ranging from Quality, Balanced, Performance, and sometimes Ultra Performance, depending on your game and version of DLSS being used. DLSS Frame Generation, if available, is a separate setting you might have to turn on.
Restart the Game (If Required): Some settings require a game restart to fully implement the changes. Follow any prompts that appear.
Adjust Settings to Your Preference: If the game allows you to configure the RTX detail levels and the DLSS setting, choose which one works best for your setup by considering performance and visual clarity.

Understanding RTX and DLSS

Ray Tracing (RTX): This rendering technique creates realistic lighting, reflections, and shadows by simulating the physical behavior of light. It dramatically improves the visual fidelity and immersion in games by adding realistic light interactions.
DLSS (Deep Learning Super Sampling): DLSS uses AI to render games at a lower resolution and then upscale the image to a higher resolution, resulting in sharper visuals at lower performance costs. This boosts FPS without drastically sacrificing image quality. Recent versions of DLSS, including DLSS 3.5 Ray Reconstruction, also enhance ray-traced images by using AI to reduce noise and improve overall image quality.
DLSS Frame Generation: This is an RTX 40 Series exclusive feature that uses AI to generate additional frames. It can significantly improve frame rates, especially in graphically demanding games.
DLAA (Deep Learning Anti-Aliasing): DLAA also uses AI, but its focus is on image quality. DLAA can make the image sharper and smoother by using the power of AI to reduce the jaggy lines. The primary focus isn’t on improving performance but on improving visual clarity.

Frequently Asked Questions (FAQs)

1. Is RTX just Ray Tracing?

While RTX is closely associated with ray tracing, it’s actually a broader platform. NVIDIA RTX encompasses technologies for ray tracing, AI acceleration (DLSS), and other advanced rendering techniques that revolutionize how we play games.

2. Can I use Ray Tracing on any GPU?

No, you need a DirectX hardware ray tracing-capable GPU to use ray tracing. Generally, this includes NVIDIA GeForce RTX 20 series and higher or AMD Radeon RX 6000 series and higher cards. Some games may offer software support for ray tracing on older cards, like the GTX 1660 Ti, but performance and feature support might be limited.

3. Do I Need RTX for DLSS?

While DLSS primarily benefits RTX series cards, earlier versions of DLSS can function on GTX cards. However, DLSS Frame Generation is exclusively for RTX 40 Series GPUs. DLSS Ray Reconstruction is supported on DX12 and Vulkan.

4. What are the Different DLSS Modes and Which Should I Use?

The DLSS Quality mode provides the highest image quality, while the Performance mode prioritizes higher FPS. There’s also usually a Balanced mode that strikes a balance between performance and image quality. The Ultra Performance mode offers the highest performance increase, but it will have more visual loss to do so. The best mode depends on your hardware and your preferences. If your setup has no problems reaching your desired frame rate, consider using DLAA or the Quality mode. If you have frame rate issues, use the Performance mode.

5. What is DLAA?

DLAA (Deep Learning Anti-Aliasing) is an AI-powered anti-aliasing technique that prioritizes image quality. It can make the image sharper, reducing the jaggies and making the visuals appear smoother, but it might cause a performance hit in some games. Use it if you prefer improved image quality over the performance boost that DLSS provides.

6. How does Nvidia DLSS work?

NVIDIA DLSS employs a deep learning model trained by NVIDIA supercomputers. It uses data from lower resolution renders and AI upscaling algorithms to create higher-resolution images with more visual clarity than other upscaling techniques, allowing for higher frame rates and improved visual fidelity. The AI model is constantly updated and improved over time by NVIDIA, with the updates being delivered to user systems through driver updates.

7. Does DLSS Improve FPS?

Yes, DLSS significantly improves FPS by allowing the game to render at lower resolutions and then reconstructing it to a higher resolution using AI, which greatly reduces performance costs. DLSS can render at 1080p or 1440p and then upscale it to 4k with very minimal loss in image quality, resulting in much higher frame rates.

8. Does DLSS Work on Every Game?

No, DLSS needs to be implemented by the developers of a game to be available. Not all games support DLSS, but the list of supported games is continually growing. Check NVIDIA’s official list for up-to-date information on supported titles.

9. What are the Downsides of Using DLSS?

Early versions of DLSS could produce a blurry or “artsy” look due to the upscaling process. However, DLSS has vastly improved, and the newer versions such as DLSS 3.5 are much better with this. DLSS also requires game-specific support, meaning not every game will have it. Also, DLSS is optimized to function with resolutions higher than 1080p. So if you are gaming on a screen with a resolution of 1080p or less, DLSS might not benefit you much.

10. How do I Turn on Ray Tracing in Cyberpunk 2077?

In Cyberpunk 2077, you can enable Ray Tracing: Overdrive by selecting that preset in Settings > Graphics > Quick Preset, or by enabling Path Tracing separately in Settings > Graphics > Ray Tracing section. Make sure your drivers are updated to the latest version (531.41 at minimum).

11. What does enabling RTX do?

Enabling RTX enables real-time ray tracing, which allows for realistic lighting, reflections, and shadows in games by calculating how light interacts within the game world.

12. How do I enable DLSS 3.0 in Cyberpunk?

To enable DLSS 3.0 in Cyberpunk 2077, go to the graphics settings and set DLSS Frame Generation to “on”.

13. What does RTX stand for?

RTX stands for Ray Tracing Texel eXtreme.

14. Is ray tracing automatically enabled?

No, ray tracing is generally not enabled by default. You typically need to enable it in the graphics settings of each individual game.

15. What are the requirements for ray tracing?

The basic requirements for ray tracing are a Windows 64-bit OS, a DirectX ray tracing capable GPU (NVIDIA GeForce® RTX 20 Series and higher, or AMD Radeon RX 6000 Series and higher), a compatible PC, an Intel Core i5 or equivalent CPU, and at least 8 GB of RAM.

By understanding how to leverage RTX and DLSS, you can significantly enhance your gaming visuals and performance. Experiment with the various settings to find the perfect balance for your hardware and enjoy the stunning experiences they offer.
