Are you trying to figure out how to enable DLSS? You’ve come to the right place. I’ll never forget the first time I saw it in action. I was at a friend’s house, and he was playing Cyberpunk 2077 on his new PC with all the ray tracing effects cranked to the max. I was baffled. “How are you getting a playable frame rate?” I asked, knowing my own rig would have choked. He just smiled and said, “DLSS, man. It’s magic.” That moment sent me down a rabbit hole of research and testing.
It turns out, getting incredible performance isn’t just about raw hardware power anymore; it’s about smart software. This guide is the result of that deep dive, my personal playbook for understanding and using NVIDIA’s game-changing AI technology. We’re going to break down what it is, how it works, and exactly how you can use it to get a massive, free performance boost in your favorite games.

What Exactly is NVIDIA DLSS and Why Should You Care?
Before we talk about flipping the switch, let’s quickly cover what DLSS even is. DLSS stands for Deep Learning Super Sampling. In simple terms, it’s a revolutionary AI technology that boosts your frame rates while maintaining crisp, high-quality visuals. I like to think of it like a master artist restoring a painting. The game renders an image at a lower, easier-to-run resolution (say, 1080p), and then the AI, which has been trained on super-high-quality offline renders, intelligently fills in the missing pixels to reconstruct a beautiful, sharp final image at your target resolution (like 4K).
What’s the “Magic” Behind DLSS?
This whole process is powered by dedicated hardware inside NVIDIA’s GeForce RTX graphics cards called Tensor Cores. These are specialized processors designed specifically for the kind of math AI and deep learning require. They allow DLSS to perform its complex calculations in real-time without bogging down the main graphics rendering pipeline. The result? You get way more frames per second than you would if your PC was trying to render every single pixel natively. For me, it’s the technology that finally made 4K gaming and ray tracing not just possible, but practical.
What Do You Need Before You Can Enable DLSS?
Now, before you go hunting through game menus, you need to make sure your setup is ready. DLSS is an exclusive NVIDIA technology, so there are a few hardware and software boxes you need to tick first.
Do I Need a Specific Graphics Card for DLSS?
Yes, this is the most important requirement. To use any version of DLSS, you absolutely must have an NVIDIA GeForce RTX graphics card. This includes:
- GeForce RTX 20-Series (e.g., RTX 2060, 2070, 2080)
- GeForce RTX 30-Series (e.g., RTX 3060, 3070, 3080)
- GeForce RTX 40-Series (e.g., RTX 4070, 4080, 4090)
Older NVIDIA cards, like the GTX 10-series or 16-series, do not have the necessary Tensor Core hardware and therefore cannot run DLSS. This is a hardware-level feature, not just a software trick.
Do All Games Support DLSS?
No, not every game has it. DLSS must be implemented by the game developers themselves. The good news is that the list of supported titles is massive and grows every single month. Major game engines like Unreal Engine and Unity have integrated it, making it easier for developers to add. You can find DLSS support in hundreds of games, from huge AAA blockbusters like Alan Wake 2 and Hogwarts Legacy to popular indie titles.
Are Updated Graphics Drivers Necessary to Enable DLSS?
Absolutely. NVIDIA is constantly improving the AI models that power DLSS. These improvements are delivered through their Game Ready Driver updates. Installing the latest driver ensures you have the most up-to-date DLSS files, which can lead to better image quality and even higher performance. I make it a habit to check for a new driver every time a big new game I’m excited about is released.
How to Enable DLSS in Your Favorite Games?
Alright, your hardware is ready, your drivers are updated, and you’re fired up to see that frame counter soar. The good news is that turning on DLSS is usually incredibly simple.
Where is the DLSS Setting Located in Most Games?
In almost every game that supports it, you’ll find the DLSS options right where you’d expect: in the main graphics or display settings menu. Here’s the typical process:
- Launch the game you want to play.
- Open the main menu (usually by pressing the Esc key).
- Navigate to Settings or Options.
- Look for a Graphics, Display, or Video tab.
- You should see an option labeled “DLSS,” “NVIDIA DLSS,” or sometimes a more generic “Upscaling” setting where you can select DLSS.
What Are the Different DLSS Modes (Quality, Balanced, Performance)?
Once you find the setting, you’ll notice you have a few choices. These modes determine the internal resolution the game renders at, which directly impacts your performance boost and final image quality.
- Quality / Ultra Quality: This mode provides the best image quality, often looking as good as or even slightly better than native resolution due to DLSS’s excellent anti-aliasing. It renders at the highest internal resolution of all the modes, giving you a solid performance boost. I always start here.
- Balanced: This is the middle ground. It offers a larger performance increase than Quality mode while still maintaining excellent visual fidelity. It’s a great “set it and forget it” option.
- Performance / Ultra Performance: These modes are for maximum FPS. They render at a lower internal resolution, giving you the biggest performance uplift. They are ideal for high-refresh-rate competitive gaming or for making demanding games playable on less powerful RTX cards. The image might be a little softer, but in the heat of the moment, you’ll probably value the smoothness more.
What Are the Advanced DLSS 3 Features?
If you’re lucky enough to own a GeForce RTX 40-Series card, you get access to DLSS 3, which is a suite of technologies that includes the core DLSS Super Resolution (the upscaling part) plus two new, exclusive features: Frame Generation and Ray Reconstruction.
What is DLSS Frame Generation and How Does It Work?
This is where things get really wild. Frame Generation uses AI to create and insert entirely new frames between the traditionally rendered ones. So, for every one frame your GPU renders, the AI is generating another one to go in between. This can dramatically multiply your frame rate, sometimes doubling it or more. The only catch is that it can add a tiny bit of input latency, which is why it automatically enables NVIDIA Reflex (another latency-reducing tech) to keep things feeling responsive. The first time I toggled this on in Microsoft Flight Simulator, my jaw hit the floor.
What is DLSS Ray Reconstruction?
Ray Reconstruction is a newer part of the DLSS 3.5 suite. It’s a smarter AI model that specifically improves the quality of ray-traced lighting. It replaces the traditional “denoiser” (a tool used to clean up the “noisy” look of raw ray tracing) with a neural network. The result is significantly more accurate and beautiful lighting, reflections, and shadows, with fewer visual artifacts. It’s a visual upgrade that also comes with a slight performance perk.
Frame Generation and Ray Reconstruction?
These are typically separate toggles right next to the main DLSS Super Resolution setting in the game’s graphics menu. You’ll see a switch for “Frame Generation” (sometimes called “DLSS G”) and another for “Ray Reconstruction.” Just remember, you’ll only see these options if the game supports them and you have an RTX 40-Series GPU.
What Are Some Best Practices for Using DLSS?
You’re now armed with the knowledge of how to enable DLSS. But to get the absolute most out of it, here are a few pro tips I’ve picked up.
Should I Pair DLSS with Other Anti-Aliasing?
No. DLSS includes its own form of high-quality temporal anti-aliasing as part of its reconstruction process. You should always disable other anti-aliasing options in the game, like TAA, MSAA, or FXAA. Leaving them on can sometimes interfere with DLSS, soften the image, and will definitely cost you performance for no visual benefit.
How to Enable DLSS for the Best Visual Experience?
My personal rule of thumb is to always start with the DLSS Quality preset. At 1440p or 4K, it often looks indistinguishable from native resolution. Only if I’m not hitting my target frame rate (like 60 FPS or my monitor’s refresh rate) do I then step down to Balanced or Performance. This ensures you’re always getting the best possible picture for your desired performance level. For a deeper academic understanding of the principles behind this kind of technology, the open-access research on real-time neural rendering at arXiv.org provides a fascinating look into the computer science involved.
Is There a Way to Manually Update the DLSS File?
This is a more advanced trick for enthusiasts. The DLSS technology is contained in a single file in your game’s directory, usually called nvngx_dlss.dll. Sometimes, a newer game will ship with a more advanced version of this file. Power users can download this newer .dll file (TechPowerUp keeps a library of them) and use it to replace the older one in another game. This can sometimes result in better image quality or performance. It’s not officially supported, so do it at your own risk, but it’s a fun way to tinker.
This process of fine-tuning is what modern PC gaming is all about. DLSS is a powerful tool in your arsenal. By understanding and learning how to enable DLSS and its various modes, you’re not just flipping a switch; you’re taking active control of your gaming experience and unlocking performance you never thought your PC had.
